The rectilinear Steiner problem is the problem of constructing the shortest rectilinear network in the plane connecting a given set of points, called terminals. The problem is known to be NP-complete in general. In this paper, we show that there is a polynomial time algorithm for solving the rectili

We consider multiple message broadcasting in tree networks. The source (considered as the root of the tree) has k messages which have to be broadcast to all nodes of the tree. In every time unit each node can send one of its already obtained messages to one of its children. A k-message broadcasting
Situations in which them is competition among possible contractor agents or possible manager agents are also considered. In all situations we assume that the contractor can choose a level of effort when carrying out the task and we would like the contractor to carry out the task efficiently without
This article deals with the problem of minimizing the transportation and inventory cost associated with the shipment of several products from a source to a destination, when a finite set of shipping frequencies is available. A mixed-integer programming model-shown to be NP-hard-is formulated for tha
