Abstract

In this paper, three types of problems for single-step searching weighted graphs are defined. They are the summation cost minimization, the bottleneck cost minimization, and a hybrid to minimize the maximum of the summation cost and the bottleneck cost. All three are shown to be NP-hard but polynomially solvable for trees. The bottleneck minimization is shown to be reducible to the summation minimization problem.
