In this paper, we present a novel hybrid approach combining particle swarm optimization (PSO) and adaptive constraint-handling technique (ACT) for solving constrained numerical and engineering optimization problems. The proposed hybrid approach simultaneously adopts particle swarm optimizer and hybrid mutation operators to generate the offspring population. Additionally, the adaptive constraint...

Efficient multiprocessor scheduling is essentially the problem of allocating a set of computational jobs to a set of processors to minimize the overall execution time. The main issue is how jobs are partitioned in which total finishing time and waiting time is minimized. Minimization of these two criteria simultaneously, is a multi objective optimization problem. There are many variations of th...

Metaheuristic algorithms, especially those based on swarm intelligence (SI), form an important part of contemporary global optimization algorithms (Kennedy and Ebarhart, 1995; Yang, 2008; Auger and Teytaud, 2010; Auger and Doerr, 2010; Blum and Roli, 2003; Neumann and Witt 2010; Parpinelli and Lopes, 2011). Good examples are particle swarm optimization (PSO) (Kennedy and Eberhart, 1995) and fir...

Software testing is a valuable and time-consuming activity that aims to improve the software quality. Due its significance, combinatorial focuses on fault identification by interaction of small amount input factors. But, deep not sufficient due time or resources availability. To select optimal test cases with least computation time, Hybrid Multi Criteria Particle Swarm Ranked Firefly Metaheuris...

The firefly algorithm has become an increasingly important tool of Swarm Intelligence that has been applied in almost all areas of optimization, as well as engineering practice. Many problems from various areas have been successfully solved using the firefly algorithm and its variants. In order to use the algorithm to solve diverse problems, the original firefly algorithm needs to be modified o...

Firefly algorithm (FA) is a new meta-heuristic optimisation algorithm that mimics the social behaviour of fireflies flying in the tropical and temperate summer sky. In this study, a novel application of FA is presented as it is applied to solve tracking problem. A general optimisation-based tracking architecture is proposed and the parameters’ sensitivity and adjustment of the FA in tracking sy...

the improvement of high-through-put gene profiling based microarrays technology has provided monitoring the expression value of thousands of genes simultaneously. detailed examination of changes in expression levels of genes can help physicians to have effi cient diagnosing, classification of tumors and cancer’s types as well as effective treatments. finding genes that can classify the group of...
