NAME
nauty-hamheuristic - 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
