Digital channel is modeled as a low pass filter; thereby the data transmitted through this band limited channel suffers from distortions. Adaptive Channel equalization involves compensation for an unknown time-varying channel which is achieved with the help of an adaptive algorithm. This update algorithm is primarily used to update the equalizer coefficients. In the present work channel equaliz...

Foraging theory originated in attempts to address puzzling findings that arose in ethological studies of food seeking and prey selection among animals. The potential utilization of biomimicry of social foraging strategies to develop advanced controllers and cooperative control strategies for autonomous vehicles is an emergent research topic. The activity of foraging can be focused as an optimiz...

A new population-based search algorithm called the Bees Algorithm (BA) is presented in this paper. The algorithm mimics the food foraging behavior of swarms of honey bees. This algorithm performs a kind of neighborhood search combined with random search and can be used for both combinatorial optimization and functional optimization and with good numerical optimization results. ABC is a meta-heu...

Trial and error method can be used to find a suitable design of a fuzzy controller. However, there are many options including fuzzy rules, Membership Functions (MFs) and scaling factors to achieve a desired performance. An optimization algorithm facilitates this process and finds an optimal design to provide a desired performance. This paper presents a novel application of the Bacterial Foragin...

Mapping of jobs to the resources in grid environment is computed under high degree of heterogeneity of resources due to which heuristic and meta-heuristic approaches are the feasible methods to scheduling in grids. In this paper we enhance the genetic based scheduling in computational grids by a bacterial foraging optimization algorithm in grid environment. This paper analyzes the run-length un...

This paper highlights the improved Adaptive Tumbling Bacterial Foraging Optimization (ATBFO) to grant better solution particularly in emission economic power dispatch issue. The proposed methodology simply takes care in solving non-convex power system issues along maintaining the requirement of all equipped constraints for healthy power delivery operation. The performances are evaluated with di...

In this paper, we explain the social foraging behavior of E. coli and M. xanthus bacteria and develop simulation models based on the principles of foraging theory that view foraging as optimization. This provides us with novel models of their foraging behavior and with new methods for distributed nongradient optimization. Moreover, we show that the models of both species of bacteria exhibit the...

Abstract— The aim of this paper is to study the tuning of a PID controller using swarm optimization techniques. In this paper, comparative performance of PSO and BF-PSO based PID controller is analyzed. PSO algorithm converges rapidly during the initial stages of a global search, but around global optimum, the search process slows down. In order to overcome this problem and to further enhance t...

With the rapid development of swarm intelligence research field, a large number of algorithms in swarm intelligence are proposed one after another. The strong points and the drawbacks of a specific swarm intelligence algorithm becomes clear to be seen when the number of its application increases. To overcome the handicaps, some hybrid methods are invented. In this review, three hybrid swarm int...

In order to further improve the ability of global path planning of coal mine rescue robot in the complex environment, a bacterial foraging algorithm-based polyclonal selection algorithm (BFA-PSA) is proposed. In order to verify the superiority of the BFA-PSA, the proposed algorithm is tested by traveling salesman problem (TSP) and compared with genetic algorithm (GA) and clonal selection algori...
