GLPK 4.18 -- Release Information
********************************
Release date: Jun 25, 2007
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 C and
organized as a callable library.
In this release:
The following new API routines were added:
glp_set_rii set (change) row scale factor
glp_set_sjj set (change) column scale factor
glp_get_rii retrieve row scale factor
glp_get_sjj retrieve column scale factor
glp_simplex solve LP problem with the simplex method (this
routine replaces lpx_simplex, which is also available
for backward compatibility)
glp_init_smcp initialize simplex method control parameters
glp_bf_exists check if the basis factorization exists
glp_factorize compute the basis factorization
glp_bf_updated check if the basis factorization has been updated
glp_get_bfcp retrieve basis factorization control parameters
glp_set_bfcp change basis factorization control parameters
glp_get_bhead retrieve the basis header information
glp_get_row_bind retrieve row index in the basis header
glp_get_col_bind retrieve column index in the basis header
glp_ftran perform forward transformation
glp_btran perform backward transformation
For description of all these routines see a new edition of the library
reference manual included in the distribution.
Type names ulong_t and uldiv_t were changed to glp_ulong and glp_uldiv
to avoid conflicts with standard type names on some platforms. Thanks
to Boris Wirtz <[EMAIL PROTECTED]> for the bug report.
Some new examples in the MathProg modeling language were added. Thanks
to Sebastian Nowozin <[EMAIL PROTECTED]>.
