A programming model is presented that goes beyond traditional object-oriented (OO) programming models by providing a construct, called an adaptive behavioral component, for capturing class collaboration. An adaptive behavioral component (ABC) represents a level of abstraction above that of a class. The implementation of a speciic task is traditionally spread out over several methods in diierent...

Recent years have seen the emergence of two main approaches to integrating constraints into logic programming. The CLP Scheme introduces constraints as basic statements over built-in computation domains. On the other hand, systems such as CHIP have introduced new inference rules, which enable certain predicates to be used for propagation thereby pruning the search tree. Unfortunately these two ...

Resumen This paper deals with an NP-hard string problem from the bio-informatics field: the repetition-free longest common subsequence problem. This problem has enjoyed an increasing interest in recent years, which has resulted in the application of several pure as well as hybrid metaheuristics. However, the literature lacks a comprehensive comparison between those approaches. Moreover, it has ...

1 Overview We had a general overview of semidefinite programming(SDP) in lecture 1, starting from this lecture we will be jumping into the theory. Some topics we will discuss in the next few lectures include: the duality theory, notion of complementary slackness, at least one polynomial time algorithm of solving SDP and application in integer programming and combinatorial optimization. Througho...

A Mathematical Program with Linear Complementarity Constraints (MPLCC) is an optimization problem where a continuously differentiable function is minimized on a set defined by linear constraints and complementarity conditions on pairs of complementary variables. This problem finds many applications in several areas of science, engineering and economics and is also an important tool for the solu...
