<br/>
<b><big><a name="Introduction" id="Introduction">Introduction</a></big></b>
<br/>
This section contains a list of the changes to CppAD during 2013
(in reverse order by date).
The purpose of this section is to
assist you in learning about changes between various versions of CppAD.
<br/>
<br/>
<b><big><a name="12-29" id="12-29">12-29</a></big></b>
<ol type="1"><li>
The include file
<a href="cppad_eigen.hpp.xml" target="_top"><span style='white-space: nowrap'>cppad_eigen.hpp</span></a>
now automatically includes <code><font color="blue">cppad.hpp</font></code>.
</li><li>
There was a problem with this automation
when <code><font color="blue">eigen</font></code> was used for the cppad <a href="testvector.xml" target="_top"><span style='white-space: nowrap'>testvector</span></a>
.
This has been fixed.
</li><li>
There was a problem with deprecated <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>InstallUnix</span></a>
(created when optional implicit constructor from any type was added).
This has been fixed by adding the
<a href="installunix.xml#--with-implicit_ctor" target="_top"><span style='white-space: nowrap'>--with-implicit_ctor</span></a>
option.
</li></ol>
<br/>
<br/>
<b><big><a name="12-27" id="12-27">12-27</a></big></b>
<br/>
The constructor from an arbitrary type to
<code><font color="blue"><span style='white-space: nowrap'>AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>></span></font></code>
was
implicit, but there was no specification to this effect.
The caused problems when using CppAD with
<a href="eigen_prefix.xml" target="_top"><span style='white-space: nowrap'>eigen 3.2</span></a>
(scheduled to be fixed in 3.3).
The default for this constructor has been changed to be
<a href="ad_ctor.xml#x.explicit" target="_top"><span style='white-space: nowrap'>explicit</span></a>
.
In addition, other
<a href="ad_ctor.xml#x.implicit" target="_top"><span style='white-space: nowrap'>implicit</span></a>
constructors
are now listed in the documentation.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>If you get a compiler error on an constructor / assignment of the form
<code><font color="blue"><span style='white-space: nowrap'><br/>
     AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>> x = </span></font><i><font color="black"><span style='white-space: nowrap'>y</span></font></i><font color="blue"><span style='white-space: nowrap'><br/>
</span></font></code>
(that used to work) try changing the constructor call to
<code><font color="blue"><span style='white-space: nowrap'><br/>
     AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>>( </span></font><i><font color="black"><span style='white-space: nowrap'>y</span></font></i><font color="blue"><span style='white-space: nowrap'> )<br/>
</span></font></code>
A deprecated alternative is to make this constructor implicit using the
<a href="cmake.xml#cppad_implicit_ctor_from_any_type" target="_top"><span style='white-space: nowrap'>cppad_implicit_ctor_from_any_type</span></a>
option during the install procedure.
<br/>
<br/>
<b><big><a name="12-26" id="12-26">12-26</a></big></b>
<br/>
Document fact that
<a href="download.xml#Compressed Archives.Monthly Versions" target="_top"><span style='white-space: nowrap'>monthly versions</span></a>
of the CppAD compressed tar file last till the end of the year.
<br/>
<br/>
<b><big><a name="12-24" id="12-24">12-24</a></big></b>
<br/>
The interface to <a href="cppad_eigen.hpp.xml" target="_top"><span style='white-space: nowrap'>eigen</span></a>
defined a function
<code><font color="blue"><span style='white-space: nowrap'><br/>
     NumTraits< CppAD::AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>> >::dummy_epsilon()<br/>
</span></font></code>
that should have been named <code><font color="blue">dummy_precision()</font></code>.
This has been fixed.
<br/>
<br/>
<b><big><a name="11-27" id="11-27">11-27</a></big></b>
<ol type="1"><li>
Fix bug when using <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimize</span></a>
with an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object containing
the <a href="sign.xml" target="_top"><span style='white-space: nowrap'>sign</span></a>
function.
</li><li>
Add <a href="atomic_norm_sq.cpp.xml" target="_top"><span style='white-space: nowrap'>atomic_norm_sq.cpp</span></a>
, an atomic function example
with domain dimension two and range dimension one.
</li></ol>
<br/>
<br/>
<b><big><a name="11-13" id="11-13">11-13</a></big></b>
<br/>
It used to be that one had to define the <code><font color="blue">std::set</font></code> version of
<a href="atomic_rev_sparse_jac.xml" target="_top"><span style='white-space: nowrap'>atomic_rev_sparse_jac</span></a>
for each atomic function that was
part of an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object that was <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimized</span></a>
.
Now the current
<a href="atomic_option.xml#atomic_sparsity" target="_top"><span style='white-space: nowrap'>atomic_sparsity</span></a>
setting is used
to determine if the <code><font color="blue">bool</font></code> or <code><font color="blue">std::set</font></code> version of
<code><font color="blue">rev_sparse_jac</font></code> is used by the optimization process.
<br/>
<br/>
<b><big><a name="11-12" id="11-12">11-12</a></big></b>
<br/>
Error detection and reporting (when <code><font color="blue">NDEBUG</font></code> is not defined)
has been added for the following case:
Using <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimize</span></a>
with <a href="atomic_base.xml" target="_top"><span style='white-space: nowrap'>atomic_base</span></a>
functions that have not defined
<a href="optimize.xml#Atomic Functions.rev_sparse_jac" target="_top"><span style='white-space: nowrap'>rev_sparse_jac</span></a>
.
<br/>
<br/>
<b><big><a name="10-29" id="10-29">10-29</a></big></b>
<br/>
The <a href="condexp.xml#Optimize" target="_top"><span style='white-space: nowrap'>optimization</span></a>
now handles nested conditional expressions.
For example, give the code
<code><font color='blue'><pre style='display:inline'>
x = CondExpLt(left_x, right_x, true_x, false_x)
y = CondExpGt(left_y, right_y, true_y, false_y)
z = CondExpEq(left_z, right_z, x, y)
</pre></font></code>
only two of the conditional expressions will be evaluated
(one will be skipped depending on the result of <code><font color="blue">left_z == right_z</font></code>).
For more details, see
<a href="wishlist.xml#Conditional Expressions.Nesting" target="_top"><span style='white-space: nowrap'>nesting conditional expressions</span></a>
<br/>
<br/>
<b><big><a name="10-23" id="10-23">10-23</a></big></b>
<ol type="1"><li>
Fix a bug in the optimization of calls to <a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
functions.
This bug existed before recent change to optimizing conditional expressions.
This required adding the
<a href="revsparsejac.xml#nz_compare" target="_top"><span style='white-space: nowrap'>nz_compare</span></a>
argument to the
reverse Jacobian sparsity pattern calculation.
For further details; see sparsity heading under conditional expressions in the
<a href="wishlist.xml#Conditional Expressions.Sparsity" target="_top"><span style='white-space: nowrap'>whish list</span></a>
.
</li><li>
Fix the deprecated autotools install (see <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>InstallUnix</span></a>
)
which was broken by the changes on 10-22.
To be specific, the
example for <a href="number_skip.xml" target="_top"><span style='white-space: nowrap'>number_skip</span></a>
was not being included.
</li></ol>
<br/>
<br/>
<b><big><a name="10-22" id="10-22">10-22</a></big></b>
<ol type="1"><li>
Add <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimization</span></a>
of conditional expressions; see
<a href="condexp.xml#Optimize" target="_top"><span style='white-space: nowrap'>CondExp</span></a>
.
</li><li>
Add a phantom argument at the beginning of the operations sequence;
<a href="seq_property.xml#size_op_arg" target="_top"><span style='white-space: nowrap'>size_op_arg</span></a>
and <a href="seq_property.cpp.xml" target="_top"><span style='white-space: nowrap'>seq_property.cpp</span></a>
.
(This helps with the optimization mentioned above.)
</li><li>
Add the function <a href="number_skip.xml" target="_top"><span style='white-space: nowrap'>number_skip</span></a>
to measure how much optimization
of the conditional expressions there is.
</li></ol>
<br/>
<br/>
<b><big><a name="10-16" id="10-16">10-16</a></big></b>
<br/>
Fix bug in <a href="wishlist.xml#Tracing" target="_top"><span style='white-space: nowrap'>Tracing</span></a>
<a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
functions.
<br/>
<br/>
<b><big><a name="10-15" id="10-15">10-15</a></big></b>
<br/>
The documentation for the class
<a href="cppad_vector.xml#vectorBool" target="_top"><span style='white-space: nowrap'>vectorBool</span></a>
was improved.
<br/>
<br/>
<b><big><a name="10-14" id="10-14">10-14</a></big></b>
<br/>
The script <a href="get_adolc.sh.xml" target="_top"><span style='white-space: nowrap'>get_adolc.sh</span></a>
was added
(for downloading and installing
<a href="https://projects.coin-or.org/ADOL-C" target="_top"><span style='white-space: nowrap'>ADOL-C</span></a>
) in the
<code><font color="blue">build</font></code> directory.
Note that this local install of Adolc requires ColPack; see
<a href="get_colpack.sh.xml" target="_top"><span style='white-space: nowrap'>get_colpack.sh</span></a>
.
In addition, the requirement that ColPack and Adolc are installed
with the same prefix was added.
<br/>
<br/>
<b><big><a name="10-13" id="10-13">10-13</a></big></b>
<br/>
Make sure that all of the
<a href="cppad.xml#Preprocessor Symbols" target="_top"><span style='white-space: nowrap'>preprocessor symbols</span></a>
,
that are not part of the CppAD API, are undefined when the
<code><font color="blue"><cppad/cppad.hpp></font></code> file concludes.
<br/>
<br/>
<b><big><a name="10-12" id="10-12">10-12</a></big></b>
<ol type="1"><li>
Change <a href="get_eigen.sh.xml" target="_top"><span style='white-space: nowrap'>get_eigen.sh</span></a>
so that it will reuse install information
when it is present.
In addition document reuse for
<a href="get_eigen.sh.xml#Reuse" target="_top"><span style='white-space: nowrap'>get_eigen.sh</span></a>
,
<a href="get_ipopt.sh.xml#Reuse" target="_top"><span style='white-space: nowrap'>get_ipopt.sh</span></a>
, and
<a href="get_sacado.sh.xml#Reuse" target="_top"><span style='white-space: nowrap'>get_sacado.sh</span></a>
.
</li><li>
Fix following <code><font color="blue">g++</font></code> error on OSX system:
<code><font color='blue'><pre style='display:inline'>
error: no match for 'operator|=' (operand types are
'std::vector<bool>::reference {aka std::_Bit_reference}' and 'bool')
Check[i * n + j] |= F2[i * n + k] & r[ k * n + j];
^
</pre></font></code>
</li></ol>
<br/>
<br/>
<b><big><a name="09-20" id="09-20">09-20</a></big></b>
<ol type="1"><li>
Add lines for <a href="atomic_base.xml" target="_top"><span style='white-space: nowrap'>atomic_base</span></a>
function documentation
to both the definition and use of each operation.
This required adding sub-headings in the example usages
corresponding to the function documentation sections.
For example; see
<a href="atomic_forward.xml#Examples" target="_top"><span style='white-space: nowrap'>atomic forward examples</span></a>
.
</li><li>
Improve the documentation for <a href="atomic_base_clear.xml" target="_top"><span style='white-space: nowrap'>atomic_base_clear</span></a>
and remove its use from the
<a href="atomic_base.xml#Examples" target="_top"><span style='white-space: nowrap'>atomic_base examples</span></a>
(because it is not needed).
</li></ol>
<br/>
<br/>
<b><big><a name="09-19" id="09-19">09-19</a></big></b>
<br/>
Add links from the <a href="atomic_base.xml" target="_top"><span style='white-space: nowrap'>atomic_base</span></a>
functions documentation
to the corresponding examples.
This required adding headings in the examples that
correspond to the function documentation sections.
For example; see
<a href="atomic_forward.xml#Examples" target="_top"><span style='white-space: nowrap'>atomic forward examples</span></a>
.
<br/>
<br/>
<b><big><a name="09-18" id="09-18">09-18</a></big></b>
<ol type="1"><li>
A segmentation fault would occur if
an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object used an <a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
function that had been deleted.
This has been fixed so that when <code><font color="blue">NDEBUG</font></code> is not defined,
an error message is generated.
</li><li>
A mistake in the documentation for
<a href="cppad_vector.xml#Memory and Parallel Mode" target="_top"><span style='white-space: nowrap'>Memory and Parallel Mode</span></a>
has been fixed.
This corresponds to the change in the specifications for
<a href="cppad_vector.xml#resize" target="_top"><span style='white-space: nowrap'>CppAD::vector::resize</span></a>
made on
<a href="whats_new_12.xml#07-30" target="_top"><span style='white-space: nowrap'>2012-07-30</span></a>
</li><li>
There was a bug during the
<a href="check_for_nan.xml" target="_top"><span style='white-space: nowrap'>checking for nan</span></a>
during
<a href="reverse.xml" target="_top"><span style='white-space: nowrap'>reverse</span></a>
mode.
This has been fixed.
</li><li>
It appears, from inspecting the Ipopt source file
<code><font color="blue">Ipopt/src/Algorithm/IpIpoptAlg.cpp</font></code> that the option <code><font color="blue">sb</font></code>
to <code><font color="blue">yes</font></code> suppress the printing of the Ipopt banner.
The Ipopt examples and tests have been changed to use this option
(although it is not in the ipopt documentation).
</li><li>
Fix the a typo in the documentation for <code><font color="blue">ipopt_solve</font></code>
<a href="ipopt_solve.xml#options.Integer" target="_top"><span style='white-space: nowrap'>Integer</span></a>
options
(<code><font color="blue">Numeric</font></code> was changed to <code><font color="blue">Integer</font></code>).
</li></ol>
<br/>
<br/>
<b><big><a name="09-07" id="09-07">09-07</a></big></b>
<br/>
There was a bug in the cumulative sum operator
(which is used by <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimize</span></a>
)
for <a href="forward.xml" target="_top"><span style='white-space: nowrap'>Forward</span></a>
orders greater than zero.
This was detected by the <a href="checkpoint.xml" target="_top"><span style='white-space: nowrap'>checkpoint</span></a>
tests
when <code><font color="blue">optimize</font></code> was used to make the
checkpoint functions faster.
The bug has been fixed and the checkpoint functions now use
optimize (and hence should be faster).
<br/>
<br/>
<b><big><a name="08-12" id="08-12">08-12</a></big></b>
<ol type="1"><li>
The ability to turn on and off checking for <a href="nan.xml" target="_top"><span style='white-space: nowrap'>nan</span></a>
in
<a href="forward.xml" target="_top"><span style='white-space: nowrap'>Forward</span></a>
mode results has been added; see <a href="check_for_nan.xml" target="_top"><span style='white-space: nowrap'>check_for_nan</span></a>
.
</li><li>
Use this option to remove the need to handel <code><font color="blue">nan</font></code> as a special
case in <a href="checkpoint.xml" target="_top"><span style='white-space: nowrap'>checkpoint</span></a>
functions that
<a href="optimize.xml#Atomic Functions" target="_top"><span style='white-space: nowrap'>atomic functions</span></a>
in within
another function is optimized.
</li><li>
Check <a href="reverse_any.xml" target="_top"><span style='white-space: nowrap'>reverse</span></a>
mode results when
<a href="check_for_nan.xml" target="_top"><span style='white-space: nowrap'>check_for_nan</span></a>
is true.
(It used to be the case that only <a href="forward_order.xml" target="_top"><span style='white-space: nowrap'>forward</span></a>
results
were checked for <code><font color="blue">nan</font></code>.)
</li></ol>
<br/>

If an <a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
function had arguments that did not affect
the final dependent variables in
<code><i><font color="black"><span style='white-space: nowrap'>f</span></font></i></code>
,
<a href="optimize.xml" target="_top"><span style='white-space: nowrap'>f.optimize()</span></a>
would fail.
This has been fixed.
In addition, documentation about using <code><font color="blue">optimize</font></code>
with <a href="optimize.xml#Atomic Functions" target="_top"><span style='white-space: nowrap'>atomic functions</span></a>
has been added.

Fix a case where the test <code><font color="blue">test_more/limits.cpp</font></code> failed because
<code><font color='blue'><pre style='display:inline'>
double inf = std::numeric_limits<double>::infinity();
double check = std::complex<double>(inf) / std::complex<float>(1.)
</pre></font></code>
can result in the imaginary part of <code><font color="blue">check</font></code> being <code><font color="blue">- nan</font></code>.
<br/>

was added.
The <a href="old_usead_2.cpp.xml" target="_top"><span style='white-space: nowrap'>old_usead_2.cpp</span></a>

The problem is that a new atomic function interface needs to be designed
with checkpointing as a particular application.
Multiple order forward mode is the first step in this direction.

There was a problem using the output operator <code><font color="blue"><<</font></code> with
and <a href="cppad_eigen.hpp.xml" target="_top"><span style='white-space: nowrap'>eigen</span></a>
matrix of <code><font color="blue">AD</font></code> elements.
This has been fixed using a template partial specialization of
<code><font color='blue'><pre style='display:inline'>
template<typename Scalar, bool IsInteger>
struct significant_decimals_default_impl
</pre></font></code>
because the original template requires definition of a implicit conversion
from the scalar type to an <code><font color="blue">int</font></code> and this is dangerous for AD types
(note that <a href="integer.xml" target="_top"><span style='white-space: nowrap'>Integer</span></a>
is used for explicit conversions).
