<br/>
This section contains a list of the changes to CppAD during 2014
(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="12-30" id="12-30">12-30</a></big></b>
<br/>
There was a bug in the <a href="cmake.xml" target="_top"><span style='white-space: nowrap'>cmake</span></a>
whereby it would sometimes mistakenly
exit with the error message
<code><font color='blue'><pre style='display:inline'>
cppad_max_num_threads is not an integer greater than or equal 4
</pre></font></code>
This has been fixed.
<br/>
<br/>
<b><big><a name="12-29" id="12-29">12-29</a></big></b>
<br/>
The example <code><font color="blue">not_complex_ad.cpp</font></code> was using the type
<code><font color="blue"><span style='white-space: nowrap'><br/>
     std::complex< CppAD::AD<double> ><br/>
</span></font></code>
and was failing to compile with the <code><font color="blue">clang</font></code> complier.
This example has been removed because it is not consistent with the
C++ standard; see
<a href="faq.xml#Complex Types" target="_top"><span style='white-space: nowrap'>complex FAQ</span></a>
.
<br/>
<br/>
<b><big><a name="12-28" id="12-28">12-28</a></big></b>
<ol type="1"><li>
Fix some warnings generated by clang 3.5 about local functions
that were not being used; e.g., sub-tests that were not being executed.
</li><li>
Fix <code><font color="blue">cmake</font></code> setting
<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>
.
Note that this option is deprecated and may eventually be removed.
</li><li>
The <code><font color="blue">clang++</font></code> compiler was optimizing out the calculations
in the <a href="time_test.cpp.xml" target="_top"><span style='white-space: nowrap'>time_test.cpp</span></a>
and <a href="speed_test.cpp.xml" target="_top"><span style='white-space: nowrap'>speed_test.cpp</span></a>
examples.
This caused these tests to hang while trying to determine how
many times to repeat the test.
This has been fixed.
</li></ol>
<br/>
<br/>
<b><big><a name="12-27" id="12-27">12-27</a></big></b>
<br/>
More work on the bug in
<a href="condexp.xml#Optimize" target="_top"><span style='white-space: nowrap'>optimizing</span></a>
conditional expressions.
<br/>
<br/>
<b><big><a name="12-26" id="12-26">12-26</a></big></b>
<br/>
A minimal example for computing cross terms in atomic operation
Hessian sparsity patterns <a href="atomic_hes_sparse.cpp.xml" target="_top"><span style='white-space: nowrap'>atomic_hes_sparse.cpp</span></a>
was added.
<br/>
<br/>
<b><big><a name="12-25" id="12-25">12-25</a></big></b>
<br/>
More work on the bug in
<a href="condexp.xml#Optimize" target="_top"><span style='white-space: nowrap'>optimizing</span></a>
conditional expressions.
<br/>
<br/>
<b><big><a name="12-23" id="12-23">12-23</a></big></b>
<br/>
The c++11 standard includes the error function <a href="erf.xml" target="_top"><span style='white-space: nowrap'>erf</span></a>
in
<code><font color="blue">cmath</font></code>.
If the c++ compiler has the error function defined in <code><font color="blue">cmath</font></code>,
the complier version of the error function is used and it corresponds to an
atomic operation.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Fix typo in tangent reverse mode theory for
<a href="tan_reverse.xml#Positive Orders Z(t)" target="_top"><span style='white-space: nowrap'>Positive Orders</span></a>
.
<br/>
<br/>
<b><big><a name="12-22" id="12-22">12-22</a></big></b>
<br/>
There was a bug related to
<a href="condexp.xml#Optimize" target="_top"><span style='white-space: nowrap'>optimizing</span></a>
conditional expressions.
This has been fixed.
<br/>
<br/>
<b><big><a name="12-17" id="12-17">12-17</a></big></b>
<br/>
Fix some compiler warnings and <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
program names
when using the deprecated <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>auto-tools</span></a>
install procedure.
<br/>
<br/>
<b><big><a name="12-16" id="12-16">12-16</a></big></b>
<br/>
If the <code><font color="blue">c++11</font></code> include file <code><font color="blue"><cstdint></font></code>
defines all the standard types, they can be used by to specify
<a href="cmake.xml#cppad_tape_addr_type.cstdint" target="_top"><span style='white-space: nowrap'>cppad_tape_addr_type</span></a>
and
<a href="cmake.xml#cppad_tape_id_type.cstdint" target="_top"><span style='white-space: nowrap'>cppad_tape_id_type</span></a>
.
<br/>
<br/>
<b><big><a name="12-15" id="12-15">12-15</a></big></b>
<br/>
Correct the title and <a href="_index.xml" target="_top"><span style='white-space: nowrap'>_index</span></a>
entries for <a href="forward_two.xml" target="_top"><span style='white-space: nowrap'>forward_two</span></a>
from first to second order.
<br/>
<br/>
<b><big><a name="11-28" id="11-28">11-28</a></big></b>
<br/>
Improve the <a href="_index.xml" target="_top"><span style='white-space: nowrap'>index</span></a>
and <code><font color="blue">search</font></code> using
a new version of the <code><font color="blue">omhelp</font></code> documentation tool.
<br/>
<br/>
<b><big><a name="11-27" id="11-27">11-27</a></big></b>
<ol type="1"><li>
Add alignment to the
<a href="ta_get_memory.xml#Alignment" target="_top"><span style='white-space: nowrap'>get_memory</span></a>
and
<a href="ta_create_array.xml#Alignment" target="_top"><span style='white-space: nowrap'>create_array</span></a>
specifications
and
<a href="thread_alloc.cpp.xml" target="_top"><span style='white-space: nowrap'>thread_alloc example</span></a>
.
</li><li>
Advance the deprecated <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>unix install</span></a>
utilities to
autoconf-2.69 and automake-1.13.4.
</li></ol>
<br/>
<br/>
<b><big><a name="09-28" id="09-28">09-28</a></big></b>
<br/>
Fix more bugs related to optimizing condition conditional expressions.
<ol type="1"><li>
Using old instead of new operator indices.
</li><li>
Not properly following dependence back through atomic operations.
</li><li>
Aborting during forward order zero, when skipping computation for a variable
that was already completed (the skip is still useful for higher orders
and for reverse mode).
</li><li>
Reverse mode not properly handling the variable number of arguments in the
conditional skip operation.
</li><li>
Reverse mode tracing not properly handling the variable number
of argument operations; i.e., conditional skip and cumulative summation.
</li></ol>
<br/>
<br/>
<b><big><a name="09-27" id="09-27">09-27</a></big></b>
<br/>
Fix a bug that occurred when
<a href="optimize.xml" target="_top"><span style='white-space: nowrap'>f.optimize</span></a>
was used with a function
<code><i><font color="black"><span style='white-space: nowrap'>f</span></font></i></code>
that contained calls to user defined <a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
operations
and <a href="condexp.xml" target="_top"><span style='white-space: nowrap'>conditional expressions</span></a>
.
<br/>
<br/>
<b><big><a name="09-25" id="09-25">09-25</a></big></b>
<br/>
Fix a bug that occurred when
<a href="optimize.xml" target="_top"><span style='white-space: nowrap'>f.optimize</span></a>
was used with a function
<code><i><font color="black"><span style='white-space: nowrap'>f</span></font></i></code>
that contained <a href="discrete.xml" target="_top"><span style='white-space: nowrap'>discrete</span></a>
functions.
<br/>
<br/>
<b><big><a name="09-21" id="09-21">09-21</a></big></b>
<br/>
Fix a typo in documentation for
<a href="reverse_any.xml" target="_top"><span style='white-space: nowrap'>any order reverse</span></a>
.
To be specific,
<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow>

<mrow><mo stretchy="false">(</mo>
<mi mathvariant='italic'>k</mi>

.
<br/>
<br/>
<b><big><a name="05-28" id="05-28">05-28</a></big></b>
<ol type="1"><li>
Change the <a href="speed_main.xml#Sparsity Options.boolsparsity" target="_top"><span style='white-space: nowrap'>boolsparsity</span></a>
so that it only affects the sparsity speed tests
<a href="link_sparse_jacobian.xml" target="_top"><span style='white-space: nowrap'>sparse_jacobian</span></a>
and
<a href="link_sparse_hessian.xml" target="_top"><span style='white-space: nowrap'>sparse_hessian</span></a>
;
i.e., it is now ignored by the other tests.
</li><li>
Improve the <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
documentation page.
</li></ol>
<br/>
<br/>
<b><big><a name="05-27" id="05-27">05-27</a></big></b>
<ol type="1"><li>
The <a href="colpack_prefix.xml#cppad_colpack.cpp" target="_top"><span style='white-space: nowrap'>cppad_colpack.cpp</span></a>
file was not being copied to the specified directory.
In addition, the specified directory was changed from an include
directory to data directory
(<code><font color="blue">cppad_colpack.cpp</font></code> is not an include file).
</li><li>
If <a href="colpack_prefix.xml" target="_top"><span style='white-space: nowrap'>colpack_prefix</span></a>
was specified, the CppAD
<a href="pkgconfig.xml" target="_top"><span style='white-space: nowrap'>pkgconfig</span></a>
file was missing some information.
This has been fixed.
</li></ol>
<br/>
<br/>
<b><big><a name="05-23" id="05-23">05-23</a></big></b>
<br/>
The <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
test instructions were converted from using
the old auto-tools <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>unix install</span></a>
instructions
to use the <a href="cmake.xml" target="_top"><span style='white-space: nowrap'>cmake</span></a>
install instructions.
These instructions should work on any system, not just unix.
<br/>
<br/>
<b><big><a name="05-22" id="05-22">05-22</a></big></b>
<ol type="1"><li>
Add multiple direction for mode
<a href="forward_dir.xml" target="_top"><span style='white-space: nowrap'>forward_dir</span></a>
and use it to speed up the forward
version of <a href="sparse_jacobian.xml" target="_top"><span style='white-space: nowrap'>sparse_jacobian</span></a>
.
Below is an example run of <a href="cppad_sparse_jacobian.cpp.xml" target="_top"><span style='white-space: nowrap'>cppad_sparse_jacobian.cpp</span></a>
results
before this change:
<code><font color='blue'><pre style='display:inline'>
cppad_sparse_jacobian_size = [ 100, 400, 900, 1600, 2500 ]
cppad_sparse_jacobian_rate = [ 2973, 431.94, 142.25, 78.64, 26.87 ]
</pre></font></code>
and after this change:
<code><font color='blue'><pre style='display:inline'>
cppad_sparse_jacobian_size = [ 100, 400, 900, 1600, 2500 ]
cppad_sparse_jacobian_rate = [ 6389, 954.26, 314.04, 180.06, 56.95 ]
</pre></font></code>
Due to the success of this change, other
<a href="wishlist.xml#Multiple Directions" target="_top"><span style='white-space: nowrap'>multiple direction</span></a>
items
were added to the wish list.
</li><li>
Improve the forward mode tracing of arguments to,
and results from, user defined <a href="atomic.xml" target="_top"><span style='white-space: nowrap'>atomic</span></a>
operations.
</li></ol>
<br/>
<br/>
<b><big><a name="05-20" id="05-20">05-20</a></big></b>
<ol type="1"><li>
Move <code><font color="blue">speed/adolc/alloc_mat.hpp</font></code> to
<code><font color="blue">speed/adolc/adolc_alloc_mat.hpp</font></code> so it has the
same name is its <code><font color="blue"># ifndef</font></code> command.
</li><li>
Fix <code><font color="blue"># ifndef</font></code> command in
<code><font color="blue">cppad/ipopt/solve_callback.hpp</font></code>.
</li><li>
Add <code><font color="blue"># ifndef</font></code> command to <code><font color="blue">test_more/extern_value.hpp</font></code>.
</li></ol>
<br/>
<br/>
<b><big><a name="05-19" id="05-19">05-19</a></big></b>
<br/>
In the files
<code><font color="blue">cppad/local/asin_op.hpp</font></code> and <code><font color="blue">cppad/local/acos_op.hpp</font></code>
there were assignments of the form <code><font color="blue">uj = 0.</font></code> where <code><font color="blue">u_j</font></code>
has type <a href="glossary.xml#Base Type" target="_top"><span style='white-space: nowrap'>Base</span></a>
.
These may have not be defined operations in certain cases and
have been converted to <code><font color="blue">uj = Base(0)</font></code>.
<br/>
<br/>
<b><big><a name="05-16" id="05-16">05-16</a></big></b>
<br/>
There was a mistake in printing the arguments for
<code><font color="blue">CSumOp</font></code> and <code><font color="blue">CSkipOp</font></code> when using the undocumented
<code><font color="blue">TRACE</font></code> option during forward mode (available in files of the form
<code><font color="blue"><span style='white-space: nowrap'>cppad/local/</span></font><i><font color="black"><span style='white-space: nowrap'>*</span></font></i><font color="blue"><span style='white-space: nowrap'>sweep.hpp/</span></font></code>
).
This has been fixed.
<br/>
<br/>
<b><big><a name="05-14" id="05-14">05-14</a></big></b>
<ol type="1"><li>
There were some global variables in the file
<code><font color="blue">cppad/local/op_code.hpp</font></code> that might have caused multiple definitions
during link time for CppAD applications.
These variables have been changed to be local so that this cannot happen.
</li><li>
There was a mistaken assert that the number of arguments for the
<code><font color="blue">BeginOp</font></code> was zero that caused an abort when using the undocumented
<code><font color="blue">TRACE</font></code> option available in files of the form
<code><font color="blue"><span style='white-space: nowrap'>cppad/local/</span></font><i><font color="black"><span style='white-space: nowrap'>*</span></font></i><font color="blue"><span style='white-space: nowrap'>sweep.hpp/</span></font></code>

and
<a href="fundeprecated.xml#capacity_taylor" target="_top"><span style='white-space: nowrap'>capacity_taylor</span></a>
functions were deprecated;
use <a href="size_order.xml" target="_top"><span style='white-space: nowrap'>size_order</span></a>
and <a href="capacity_order.xml" target="_top"><span style='white-space: nowrap'>capacity_order</span></a>
instead.
</li><li>
The documentation for <a href="forward.xml" target="_top"><span style='white-space: nowrap'>forward</span></a>
and the examples
<a href="forward.cpp.xml" target="_top"><span style='white-space: nowrap'>forward.cpp</span></a>
, <a href="forward_order.cpp.xml" target="_top"><span style='white-space: nowrap'>forward_order.cpp</span></a>
, have been improved.
To be more specific, <a href="forward_order.xml" target="_top"><span style='white-space: nowrap'>forward_order</span></a>
now references the special
cases <a href="forward_zero.xml" target="_top"><span style='white-space: nowrap'>forward_zero</span></a>
, <a href="forward_one.xml" target="_top"><span style='white-space: nowrap'>forward_one</span></a>

<br/>
The
<a href="cppad_vector.xml#Assignment.Move Semantics" target="_top"><span style='white-space: nowrap'>move semantics</span></a>
version of the <code><font color="blue">CppAD::vector</font></code> assignment statement
was not checking vector sizes.
This has been fixed so that things work the same with compilers
that do not have move semantics.
(Note that with move semantics, no extra memory allocation is done
even if the target vector has a different size.)
<br/>
<br/>
<b><big><a name="03-09" id="03-09">03-09</a></big></b>
<br/>
The documentation links
<code><font color="blue">forwardzero</font></code>, <code><font color="blue">forwardone</font></code>, and <code><font color="blue">forwardany</font></code>
have been changed to
<a href="forward_zero.xml" target="_top"><span style='white-space: nowrap'>forward_zero</span></a>
, <a href="forward_one.xml" target="_top"><span style='white-space: nowrap'>forward_one</span></a>
,
and <a href="forward_order.xml" target="_top"><span style='white-space: nowrap'>forward_order</span></a>
respectively.
This may affect links from other web pages to the CppAD documentation.
