* The core LP solver based on the dual simplex method was re-implemented and now it provides both phases I and II. * New API routines. * For description of these new routines see the reference manual included in the distribution. * The following API routines are deprecated: lpx_scale_prob, lpx_std_basis, lpx_adv_basis, lpx_cpx_basis. * Necessary changes were made in memory allocation routines to resolve portability issues for 64-bit platforms. * New version of the routine lpx_write_pb to write problem data in OPB (pseudo boolean format) was added to the package. * Two new makefiles were added to build the package for 32- and 64-bit Windows with Microsoft Visual Studio Express 2008. * Two new makefiles were added to build the package with Digital Mars C/C++ 8.50 and Open Watcom C/C++ 1.6 (for 32-bit Windows). |
