Title: On the Wiener Index Spanning Tree Problem

Speaker: Sheng-Lung Peng, National Dong Hwa University, Hualien 974, Taiwan

Abstract: The Wiener index was first proposed in chemistry for characterizing molecular structures based on the count of path distances between carbon atoms. Latter, it was defined in graph theory as follows. The Wiener index of a graph is the sum of all pairwise distances of vertices of the graph. In this talk, we consider the Wiener index spanning tree problem. Given a graph G, the maximum (minimum) Wiener index spanning tree problem on G is to find a spanning tree T of G such that the Wiener index of T is the maximum (minimum) among all possible spanning trees of G. Recently, it has been shown that the minimum Wiener index spanning tree of a wireless sensor network is better than its minimum spanning tree while considering the routing issue. In this talk, we consider the algorithmic results for the Wiener index spanning tree problem.

Title: Bio-Inspired Optimization of Type-2 Fuzzy Logic Systems

Speaker: Oscar Castillo, Tijuana Institute of Technology, Tijuana, Mexico

Abstract: The design of Type-2 fuzzy logic systems is a complex task and in general achieving an optimal configuration of structure and parameters is time consuming and rarely found in practice. For this reason the use of bio-inspired meta-heuristics offer a good hybrid solution to find near optimal designs of type-2 fuzzy logic systems in real world applications. In particular, type-2 fuzzy control offers a real challenge because the problems in this area require very efficient and accurate solutions; in particular this is the case for robotic applications. Another important application of type-2 fuzzy logic is in pattern recognition problems. In this talk we present a general scheme for optimizing type-2 fuzzy systems with bio-inspired optimization techniques, like ant colony optimization, the chemical reaction algorithm, bee colony optimization and others.
