-checkp <checkpoint file> if mplrs is terminated by -stop or -time then it can be restarted using this <checkpoint file> and -restart

-countonly don't output vertices/rays/facets, just count them

-freq <file> store frequency data in <file> for use by gnuplot, see below

-hist <file>store parallelization data in <file> for use by gnuplot, see below

-id <initial depth> [2] the depth of the original tree search to populate the job list L

-lmax <int>[lmin] if job list |L|>np*lmax then then maxc is replaced by maxc*scale

-lmin <int>[3] if job list |L|<np*lmin then the maxd parameter is set for all producers

-maxbuf <n>[500] controls maximum size of worker output buffers

-maxc <maxcobases>[50 (*scale)] a producer stops and returns all subtrees that are not leaves to L after generating  maxc nodes   

-maxd <depth>[0] a producer returns all subtrees that are not leaves at depth maxd. Zero if not used

-minheight jobs are scheduled in increasing order by height in the search tree (default is LIFO)

-queue jobs are scheduled in FIFO order (default is LIFO)

-restart <checkpoint file> restart mplrs using previously created <checkpoint file>. If used with -checkp file names should be different!

-scale <int>[100] used by lmax

-stop <stopfile> terminate mplrs if a file with name <stopfile> is created in the current directory

-stopafter <n> exit after approximately <n> cobases have been computed (no guarantee about how many vertices/rays/facets computed)

-temp <prefix>[/tmp/] store a temporary file for each process. Should be specified if /tmp not writeable. Using " -temp  ./ " will write temporary files to the current directory

-time <seconds> terminate mplrs after <seconds> of elapsed time

-j <int>[1] if non-zero splits the run into <int> jobs per worker, over-riding rows and lastrows

-lastp <int>[10] the percentage of jobs to use lastrows

-lastrows <int>[10] the number of rows for the last lastp jobs

-minrep removes redundant inequalities, finds hidden linearities and outputs a minimum representation of the input file. This ignores any project or eliminate option present in the input file

-rows <int>[60] the number of rows per job
