The paper suggests an exhaustive search algorithm for finding
Hamiltonian circuits in an undirected graph based on depth-first
search and working successfully on sparse graphs. The method is
based on the idea not to search all palms in the graphs but only
those which are not branched.
Tutte's 46 vertices graph searching took less than 3 minutes on EC-
1022 computer.
