Linear Program Solver Files

Linear Program Solver (LiPS) is an optimization package intended for solving linear, integer and goal programming problems. The main features of the LiPS are:

· LiPS solver is based on the efficient implementation of the modified simplex method; 
· LiPS provides not only an answer, but a detailed solution process as a sequence of simplex tables, so you can use it in studying (teaching) linear programming. 
· LiPS provides the procedures of sensitivity analysis, which enable us to study the behavior of the model when you change its parameters, including: analysis of changes in the right sides of constraints, analysis of changes in the coefficients of the objective function, the analysis of changes in the column / row of the technology matrix. Such information may be extremely useful in the practical application of LP models. 
· LiPS provides the methods of the goal programming, including the lexicographic and weighted GP methods. Goal programming methods are intended for solving multi-objective optimization problems.
