In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

In this paper, we present an exact algorithm to find all extreme supported nondominated points of multiobjective mixed integer programs. The algorithm uses a composite linear objective function and ...

This paper presents an algorithm for finding all shortest routes from all nodes to a given destination in N-node general networks (in which the distances of arcs can be negative). If no negative loop ...
