NAME
ppl_lpsol - a PPL-based mixed integer programming problem solverSYNOPSIS
ppl_lpsol [OPTION]... [FILE]DESCRIPTION
Reads a file in MPS format and attempts solution using the optimization algorithms provided by the PPL.See the GNU Linear Programming Kit: Reference Manual (Version 4.31) for information on the MPS format.
OPTIONS
- -c, --check[=THRESHOLD] checks the obtained results;
- optima are checked with a tolerance of THRESHOLD (default 1e-09)
- -i, --incremental
- solves the problem incrementally
- -m, --min
- minimizes the objective function
- -M, --max
- maximizes the objective function (default)
- -n, --no-optimization
- checks for satisfiability only
- -r, --no-mip
- consider integer variables as real variables
- -CSECS, --max-cpu=SECS
- limits CPU usage to SECS seconds
- -RMB, --max-memory=MB
- limits memory usage to MB megabytes
- -h, --help
- prints this help text to stdout
- -oPATH, --output=PATH
- appends output to PATH
- -e, --enumerate
- use the (expensive!) enumeration method
- -pM, --pricing=M
- use pricing method M for simplex (assumes -s); M is an int from 0 to 2, default 0: 0 --> steepest-edge using floating point 1 --> steepest-edge using exact arithmetic 2 --> textbook
- -s, --simplex
- use the simplex method
- -t, --timings
- prints timings to stderr
- -v, --verbosity=LEVEL
- sets verbosity level (from 0 to 4, default 3): 0 --> quiet: no output except for errors and
- explicitly required notifications
- 1 --> solver state only 2 --> state + optimal value 3 --> state + optimal value + optimum location 4 --> lots of output
- -V, --version
- prints version information to stdout
AVAILABILITY
The latest version of the Parma Polyhedra Library and all the documentation is available at http://www.cs.unipr.it/ppl/ .NOTES
The options -CSECS (--max-cpu=SECS) and -t (--timings) are not available on some platforms.AUTHOR
