DownloadLinear Program Solver (LiPS) is an optimization package oriented on solving linear, integer and goal programming problems.
The main features of LiPS are:
● LiPS is based on the efficient implementation of the modified simplex method that solves large scale problems.
● LiPS provides not just an answer, but a detailed solution process as a sequence of simplex tables, so you can use it for studying/teaching linear programming.
● LiPS gives sensitivity analysis procedures, which allow us to study the behaviour 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, analysis of changes in the column/row of the technology matrix. Such information may be extremely useful for the practical application of LP Models.
● LiPS provides methods of goal programming, including lexicographic and weighted GP methods, which are oriented on multi-objective optimisation.

The results are presented as integer fractions rather than floating point numbers and I see no option to change that. I have to spend a lot of time converting results to floating point with a calculator. I really hate it when people get the difficult part of a project right and the easy part wrong. And, there is no help, just a pretend help with "?" and clicking on it does nothing. I don't like being jerked around either.
