man glpsol (Commandes) - GLPK linear programming/MIP solver

NAME

GLPSOL - GLPK linear programming/MIP solver

SYNOPSIS

glpsol [options...] filename

DESCRIPTION

General options:

--glp: read LP/MIP problem in GNU LP format
--mps: read LP/MIP problem in fixed MPS format (default)
--freemps: read LP/MIP problem in free MPS format
--cpxlp: read LP/MIP problem in CPLEX LP format
--math: read LP/MIP model written in GNU MathProg modeling language
-m filename, --model filename: read model section and optional data section from filename (the same as --math)
-d filename, --data filename: read data section from filename (for --math only); if data section follows model section in the same file, this option is ignored
-y filename, --display filename: send display output to filename (for --math only); by default the output is sent to stdout
--min: minimization
--max: maximization
--scale: scale the problem (default)
--noscale: do not scale the problem
--simplex: use simplex method (default)
--interior: use interior point method (for pure LP only)
-o filename, --output filename: write solution to filename in plain text format
--bounds filename: write sensitivity bounds to filename in plain text format (LP only)
--tmlim nnn: limit solution time to nnn seconds
--memlim nnn: limit available memory to nnn megabytes
--check: do not solve the problem, check input data only
--name probname: change problem name to probname
--plain: use plain names of rows and columns (default)
--orig: try using original names of rows and columns (default for --mps)
--wglp filename: write problem to filename in GNU LP format
--wmps filename: write problem to filename in fixed MPS format
--wfreemps filename: write problem to filename in free MPS format
--wcpxlp filename: write problem to filename in CPLEX LP format
--wtxt filename: write problem to filename in plain text format
-h, --help: display this help information and exit
-v, --version: display program version and exit

Options specific to simplex method:

--std: use standard initial basis of all slacks
--adv: use advanced initial basis (default)
--bas filename: read initial basis from filename in MPS format
--steep: use steepest edge technique (default)
--nosteep: use standard "textbook" pricing
--relax: use Harris' two-pass ratio test (default)
--norelax: use standard "textbook" ratio test
--presol: use presolver (default; assumes --scale and --adv)
--nopresol: do not use presolver
--wbas filename: write final basis to filename in MPS format

Options specific to MIP:

--nomip: consider all integer variables as continuous (allows solving MIP as pure LP)
--first: branch on first integer variable
--last: branch on last integer variable
--drtom: branch using heuristic by Driebeck and Tomlin (default)
--mostf: branch on most fractional variable
--dfs: backtrack using depth first search
--bfs: backtrack using breadth first search
--bestp: backtrack using the best projection heuristic (default)
--bestb: backtrack using node with best local bound
