Method Detail

getBest

Permutation getBest()

Get the best permutation found.

Returns:

the permutation that gives the maximal half-matrix string

getAutomorphismPartition

Partition getAutomorphismPartition()

The automorphism partition is a partition of the elements of the group.

Returns:

a partition of the elements of group

getAutomorphismGroup

PermutationGroup getAutomorphismGroup()

Get the automorphism group used to prune the search.

Returns:

the automorphism group

getFirst

Permutation getFirst()

Get the first permutation reached by the search.

Returns:

the first permutation reached

firstIsIdentity

boolean firstIsIdentity()

Check that the first refined partition is the identity.

Returns:

true if the first is the identity permutation
