In recent research works, metaheuristic methods have been widely used to minimize THD in inverters, these provide better computation time and effective results compared classical methods. This paper presents a systematic analysis with comprehensive coverage of applied multilevel inverters. The search focused on the characteristics inverters articles (topologies, levels, loads evolutionary metho...
Teaching students with sensory disabilities have always been of interest to scholars and educational experts. One of the sensory disabilities is blindness. It should be noted that traditional methods of training these individuals do not have the necessary efficiency and it causes the reduction of motivation in the students. Thus, an evolutionary approach is necessary. Most computer games as i...
In recent years, the spectral analysis has been one of the most important research areas in remote sensing, which has received different traditional solutions. Most of these methods have several special conditions to work well. However, they suffer from the problems such as sticking in local optimum and having sensibility to parameters initialization. Although the Evolutionary Computation (EC) ...
Stochastic optimization methods such as evolutionary algorithms and Markov Chain Monte Carlo methods usually involve a Markov search of the optimization domain. Evolutionary annealing is an evolutionary algorithm that leverages all the information gathered by previous queries to the cost function. Evolutionary annealing can be viewed either as simulated annealing with improved sampling or as a ...
Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
Imperialist Competitive Algorithm (ICA) is considered as a prime meta-heuristic algorithm to find the general optimal solution in optimization problems. This paper presents a use of ICA for automatic clustering of huge unlabeled data sets. By using proper structure for each of the chromosomes and the ICA, at run time, the suggested method (ACICA) finds the optimum number of clusters while optim...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
Evolutionary approaches to molecular docking typically hybridize with local search methods, more specifically, the Solis-Wet method. However, some studies indicated that local search methods might not be very helpful in the context of molecular docking. An evolutionary algorithm with proper genetic operators can perform equally well or even outperform hybrid evolutionary approaches. We show tha...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
