LP file extension - LP88 linear programming for the IBM-PC file
What is lp file? How to open lp files?
File type specification:
The LP file extension is associated with LP88, a general purpose system for solving linear programs with up to 3000 constraints, 15000 variables, and 64000 nonzeros.
LP88 is a compiled Turbo Pascal program that employs the revised simplex algorithm within a state-of-the-art code to provide a fast and efficient linear programming system for the IBM PC. It can read and write to Lotus/Symphony spreadsheets.
LP88 runs on IBM PC, AT, 386, 486 and compatibles.
