GLPK 4.65 Release Information
*****************************
Release date: February 16, 2018
GLPK (GNU Linear Programming Kit) is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems. It is a set of routines written in ANSI C89 and
organized as a callable library.
In this release:
The following new API routines for LP/MIP preprocessing were
added:
glp_npp_alloc_wksp allocate the preprocessor workspace
glp_npp_load_prob load original problem instance
glp_npp_preprocess1 perform basic LP/MIP preprocessing
glp_npp_build_prob build resultant problem instance
glp_npp_postprocess postprocess solution to resultant problem
glp_npp_obtain_sol obtain solution to original problem
glp_npp_free_wksp free the preprocessor workspace
See doc/npp.txt for detailed description of these API routines.
A new, more robust implementation of locally valid simple cover
cuts was included in the MIP solver.
The API routine glp_init_iocp was changed to enable long-step
option of the dual simplex by default.
