Popis:	Multi-objective optimization problem is an important part in solving a wide number of engineering and scientific applications. To-date, most of the research has been conducted in solving static multi-objective problems where the decision variables and/or the objective functions do not change over a period of time. In a dynamic environment, the particles non dominated solution set during a specific iteration may no longer be valid due to change in the underlying system. As a result, traditional techniques for solving static multi-objective functions cannot be applied for solving dynamic multi-objective functions. Further, with the increase in the number of variables/objective functions, a single system based optimizer will take a long time to compute the non-dominated solution set. In this paper, we present a peer-to-peer distributed particle swarm optimization algorithm that tracks the change in the underlying system and is able to produce a diversified and dense non- dominated set using a network of peer-to-peer system. Our algorithms are tested using a set of known benchmark problems and results are reported. To our knowledge, this algorithm is the first of its kind in the areas of peer-to-peer particle swarm optimization.
