LPDL (Linear Programming Definition Language)

Note: this repo, along with the rest if JAM-C are still under development and they are subject to change drastically.

This repo contains the parser and the definition language specification for the linear programming solver by JAM-C

Language Specification

A problem file consist of the objective function along with whether it should be minimized or maximized on, always, the first non-empty line.

The rest lines are assumed to be the constrains.

You can write the cost function along with the constraints as typical equations

Restring a variable to be an integer could be done by

making a new line with var_name: int

// are used for comments All spaces are ignored

An example is provided in example.txt

You do not need to define the variables, which seems redundant in LP problem format

Parser

The main.ts file contains the source code that convert a problem file into a format that can be used to the solver in https://github.com/JAM-C/lp-solverlib

The parser could be used with cargo run main.ts -- example.txt
