nauty-hamheuristic(1) try to find hamiltonian cycles in any graphs

SYNOPSIS

hamheuristic [,-sgu/] [,-vq/] [,-L#/] [,-t#/] [,infile /[,outfile/]]

DESCRIPTION

Apply a heuristic for finding hamiltonian cycles.
Output those which are unsuccessful.
-s
force output to sparse6 format
-g
force output to graph6 format If neither -s or -g are given, the output format is determined by the header or, if there is none, by the format of the first input graph.
-u
Suppress output to outfile, give statistics instead.
The output file will have a header if and only if the input file does.
-p
Be content with a hamiltonian path
-v
Give a cycle or path if one is found.
-L# Limit number of sideways steps (default 1000+5*n)
-t# Try # times (default 1)
-q
suppress auxiliary information
