  1. Fix problem with import cppad_ in 20111017 version.
  2. Change runge_kutta_4_cpp.py to use optimize and to check that using pycppad is always more than 100 times faster than straight python for this test case.

Add tape optimization; see optimize .

10-16
  1. Add the conditional expressions; see condexp .
  2. Use newer version of CppAD that fixes warnings found by g++ version 4.6.1.

The --undef option is not available to ./setup.py build so ./setup.py build was changed to ./setup.py build_ext in the build instructions .

  1. There was a problem with the pycppad install instructions. To be specific, the debug build was not being installed because of the presence of --inplace in the example setup.py command. This has been fixed in the new debug build instructions .
  2. Change from using cppad-20100101.5 to using cppad-20110101.2.gpl.tgz; see CppAD whats_new .
  3. Use external sub directory of current working directory, instead of $HOME/install, for default directory that holds a local copy of CppAD; see cppad_parent_dir under Required Setup Information .
  4. Add boost_python_include_dir to list of Required Setup Information .
