@section changelog History
- Version 1.6 (2008-11-02):
- Improved line-search algorithm with strong Wolfe condition, which was
contributed by Takashi Imamichi. This routine is now default for
::LBFGS_LINESEARCH_BACKTRACKING. The previous line search algorithm
with regular Wolfe condition is still available as
::LBFGS_LINESEARCH_BACKTRACKING_LOOSE.
- Configurable stop index for L1-norm computation. A member variable
::lbfgs_parameter_t::orthantwise_end was added to specify the index
number at which the library stops computing the L1 norm of the
variables. This is useful to prevent some variables from being
regularized by the OW-LQN method.
- A sample program written in C++ (sample/sample.cpp).
- Version 1.5 (2008-07-10):
- Configurable starting index for L1-norm computation. A member variable
::lbfgs_parameter_t::orthantwise_start was added to specify the index
