DB2 and DB2A: Two useful tools for constructing Hamiltonian circuits
The paper presents a procedure, called DB2A, for constructing a Hamiltonian circuit (HC) in a general directed graph. Application examples and a completely developed example problem are included. An appendix recalls the features of DB2, used here as a subprocedure of DB2A, and finding a Hamiltonian cycle in undirected graphs.
