An lp file extension is related to the LP88 linear programming for the IBM-PC file format.
LP file extension - LP88 linear programming for the IBM-PC data
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.
This lp file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
