This paper presents the performance of Integrated Bacterial Foraging Optimization and Particle Swarm Optimization (IBFO_PSO) technique in MANET routing. The BFO is a bioinspired algorithm, which simulates the foraging behavior of bacteria. It is effectively applied in improving the routing performance in MANET. In results, it is proved that the PSO integrated with BFO reduces routing delay, ene...

In this article, we present new method of hybrid intelligent systems. Intelligent systems are very useful for prediction in any situation and are a new wave of embedded and real-time systems that are highly connected, with massive processing power and performing complex process. Here, we present a method of hybrid systems for prediction of the roughness of robot laser hardened specimens, if we ...

This paper considers the shortest path problem with fuzzy arc lengths. According to different decision criteria, the concepts of expected shortest path, a-shortest path and the most shortest path in fuzzy environment are originally proposed, and three types of models are formulated. In order to solve these models, a hybrid intelligent algorithm integrating simulation and genetic algorithm is pr...

  In this paper, we present the stochastic version of Maximal Covering Location Problem which optimizes both location and allocation decisions, concurrently. It’s assumed that traveling time between customers and distribution centers (DCs) is uncertain and described by normal distribution function and if this time is less than coverage time, the customer can be allocated to DC. In classical mod...

This paper considers to locate multiple new uncapacitated facilities on a plane bounded by a convex polygon under minisum, maximin and minimax criteria to meet fuzzy demands of customers. Some fuzzy programming models are initiated for this problem, where Euclidean distances are assumed as the scenario. And a hybrid intelligent algorithm is designed for solving the proposed models.

This issue of International Journal of Intelligent Systems includes extended versions of selected papers from the 4th International Conference on Soft Computing, held in Iizuka, Japan, September 30]October 5, 1996. The topic of the special issue is ‘‘Hybrid Intelligent Adaptive Systems.’’ Research on hybrid systems is one of the key issues of developing intelligent systems and it can apply a wi...

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 ...

This paper discusses the minimax location problem with fuzzy locations of customers on a plane bounded by a convex polygon under a minmax criterion. Three types of fuzzy programming are presented for this problem according to different criteria, and Euclidean distances are assumed as the scenario. For solving the proposed models, a hybrid intelligent algorithm is designed.
