Description
Summary:This paper presents a performance evaluation of a Vector Evaluated Gravitational Search Algorithm (VEGSA) for multi-objective optimization problems. The VEGSA algorithm uses a number of populations of particles. In particular, a population of particles corresponds to one objective function to be minimized or maximized. Simultaneous minimization or maximization of every objective function is realized by exchanging a variable between populations. The results show that the VEGSA is outperformed by other multi-objective optimization algorithms and further enhancements are needed before it can be employed in any application.
