minimum spanning treetwo‐phase methodsThis paper presents a new two‐phase algorithm for the bi‐objective minimum spanning tree (BMST) problem. In the first phase, it computes the extreme supported efficient
We consider now some other network optimization problems, in which the objective is to compute a shortest path, cycle, tree, or other graph, subject to various types of constraints. We focus primarily on two classes of problems: those of finding minimum-cost trees or tours that span some or...
Begin by identifying a focus question and exploring the ways in which it manifests before splitting into five teams who will each consider the problem using a different method: escape, reversal, exaggeration, distortion or wishful. Teams develop a problem objective and create ideas in line with t...

The mcMST package for the R programming language contains several methods for solving the multi-criteria spanning tree problem (mcMST).Key features of the mcMST package are:A multi-objective version of Prim's algorithm. Evolutionary multi-objective algorithms (based on the Prüfer-encoding or ...

We consider the problem of grooming paths in all-optical networks with tree topology so as to minimize the switching cost, measured by the total number of used ADMs. We first present efficient approximation algorithms with approximation factor of 2 ln (δ ...
Therefore, the main objective of this work is to study and analyze the state of the literature in the field of MRS-oriented path planning and, with this work, to complement previous studies related to this field. This survey collects and analyzes a set of techniques, methods and algorithms ...
where the inequalities g(x)≥b and x≥0 are the constraints that specify a convex polytope over which the objective function c(x) is to be minimized, and f is the finite set of feasible solutions x that satisfy the constraints. There are many real-life problems (e.g., vehicle routing...
