NAME

       isofilter - removes isomorphic structures from mace4(1) models

SYNOPSIS

       isofilter [options] < input-file > output-file
       isofilter0 [options] < input-file > output-file
       isofilter2 [options] < input-file > output-file

DESCRIPTION

       This manual page documents briefly the isofilter, isofilter0 and isofilter2 commands.

       If  mace4(1)  produces  more  than  one  structure,  some  of  them  are very likely to be
       isomorphic to others. The program isofilter can be used to remove isomorphic structures.

ALGORITHM

       There are multiple isofilter variants providing alternative algorithms.

       isofilter
              Uses Occurrence Profiles algorithm.

       isofilter2
              Uses Canonical Forms algorithm.

OPTIONS

       A summary of options is included below.

       ignore_constants
              Ignore all constants during the isomorphism tests.

       check <operations>
              Consider only the listed operations in the isomorphism tests.

       output <operations>
              Output only the listed operations.

       wrap   Enclose the resulting structures in list(interpretations). ... end_of_list.
