Problem Statements for k-Node Shortest Path and k-Node Shortest Cycle in a Complete Graph*
The author formulates mixed Boolean linear programming problems to find the shortest route and the shortest cycle that pass through the given number of nodes in a complete graph. Their special cases provide formulations of problems for finding the shortest Hamiltonian path and the shortest Hamiltonian cycle. The problems include no more than 2n2 variables and no more than (n + 1)2 constraints, where n is the number of nodes of the complete graph.
