Seas and oceans are the most important sources of renewable energy in the world. The main purpose of this paper is to use an appropriate control strategy to improve the performance of point absorbers. In this scheme, considering the high uncertainty in the parameters of the power take-off system in different atmospheric conditions, a new improved black hole algorithm is introduced to tune fuzzy...

The main purpose of this research is portfolio optimization in Tehran securities exchange using the black hole algorithm and the Gravitational Research algorithm. We also propose an algorithm named Hybrid Algorithm which combines the two algorithms above to cover the weaknesses of these two algorithms. Finally we compare the results with the Markowitz model and choose the optimal algorithm.<br ...

In this paper we improved efficiency of black holes algorithm with using of fuzzy Hawking radiation. A black hole is a region of space-time whose gravitational field is so strong that nothing which enters it, not even light, can escape. In the black holes algorithm there is a phase with name Hawking radiation. In this phase the position of the some black hole changes a little. This phase as equ...

Software clustering is the process of organizing software units into appropriate clusters so as to efficiently modularize complex program structure. In this paper, we investigate the use of hybrids of Black Hole algorithm (developed using weighted aggregation, auxiliary archive and Genetic Algorithm) to optimize multiple objectives for clustering of android mobile applications. It is empiricall...

MANETs are accessible to various attacks [1]. Black hole attack is one kind of routing disturbing attacks [13] and can destroy a MANET partially or totally. In this paper Fuzzy Logic techniques have been used to detect black hole attacks and find out secure routing in wireless ad hoc networks. The proposed heuristic successfully detects the black hole in the network and this information is pass...
