NAME¶

TOPCOM - triangulations of point configurations and oriented matroids

DESCRIPTION¶

TOPCOM programs share a command-line parsing library. Therefore, all TOPCOM programs accept the following options. Note that some options are not relevant to all TOPCOM programs.

Options concerning shell output:

-h, --help

summarize the program options.

-v

write verbose information to stderr.

--reportfrequency [N]

report every Nth new triangulation.

-d

write debug information to stderr.

--heights

write height vectors for triangulations to stdout (implies --regular).

--flips

write flips as pairs of triangulation IDs to stdout.

Options for checking input:

--checktriang

check any given triangulations for correctness.

Options for reporting properties of discovered triangulations:

--flipdeficiency

report flip deficiency in triangulations to stderr.

--checkfrequency [N]

check for regularity every Nth triangulation and exit if regular.

Options concerning which triangulations are output (no influence on exploration):

--cardinality [N]

count/output only triangulations of cardinality N.

--nonregular

count/output only non-regular triangulations.

Options concerning which triangulations are explored:

--regular

consider only regular triangulations.

--noinsertion

never use a point that is unused in the seed triangulation.

--reducepoints

try to remove the number of use points, reported to stderr.

--keepcard

never change the cardinality of triangulations by flipping.

Options concerning symmetries:

--affine

assume that given symmetries are affine.

--nosymmetries

ignore symmetries.

Options for dumping and reading the status of an interrupted computation:

--dump

dump status of previous computation (last completed BFS round) into file.

--dumpfile [FILENAME]

set dump file name to FILENAME (default: "TOPCOM.dump").

--dumpfrequency [N]

dump each Nth completed BFS round (default: 1).

--dumprotations [N]

dump into N rotating files.

--read

read status of previous computation (last completed BFS round) from file.

--readfile [FILENAME]

set dump file name to read to FILENAME (default: "TOPCOM.dump").

Options concerning internal behaviour:

--memopt

try to reduce memory consumption.

--chirocache [N]

set the chirotope cache to N elements.

--localcache [N]

set the cache for local data to N elements.

--soplex

use soplex for regularity checks. Note that soplex is not available from Fedora due to its non-free license.
