The GLPK package is intended for solving linear
programming (LP) and mixed integer linear
programming (MIP) problems. It is a set of
routines organized in the form of a library and
written in the ANSI C programming language.

An advanced MIP solver was implemented. Three
built-in functions were added to MathProg (sin,
cos, atan). Some bugs were fixed. New examples on
MathProg were included.
