In recent years, significant research efforts have been devoted to the optimal planning of power systems. Substation Expansion Planning (SEP) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. The large number of design variables, and combination of discrete and continuous variables makes the substation expansion planning a very challenging problem. So far, various methods have been presented to solve such a complicated problem. Since the bacterial foraging optimization algorithm (BFOA) has been proper results in studies of power systems, and has not been applied to SEP problem yet, this paper develops a new BFO-based method to solve the SEP problem. The technique discussed in this paper uses BFOA to simultaneously optimize the sizes and locations of both the existing and new installed substation and feeders by considering reliability constraints. To clarify the capabilities of the presented method a typical network is considered and the results of applying GA and BFOA on the network are compared. The simulation results demonstrate that the BFOA has the potential to find more optimal results than the other algorithm under the same conditions. Also, the fast convergence, consideration of real-world networks limitations as problem constraints and simplicity in applying to large scale networks are the main features of the proposed method.

Selection of relevant features is an open problem in Brain-computer interfacing (BCI) research. Sometimes, features extracted from brain signals are high dimensional which in turn affects the accuracy of the classifier. Selection of the most relevant features improves the performance of the classifier and reduces the computational cost of the system. In this study, we have used a combination of bacterialforagingoptimization and Learning Automata to determine the best subset of features from a given motor imagery electroencephalography (EEG) based BCI dataset. Here, we have employed Discrete Wavelet Transform to obtain a high dimensional feature set and classified it by Distance Likelihood Ratio Test. Our proposed feature selector produced an accuracy of 80.291% in 216 seconds.

The type-1 fuzzy sets theory was proposed to handle uncertainty in control systems, but some cases showed some liabilities of type-1 fuzzy sets when faced with unpredictable disturbance and uncertainties. Therefore, type-2 fuzzy sets were introduced and extended while providing more degrees of freedom in designing criteria. The most important specification of type-2 fuzzy sets is the interval between a superior membership function and an inferior membership function, which is called the footprint of uncertainty. This paper presents a bacterialforagingoptimization approach for optimizing the parameterized membership function. The above criterion is applied to an automatic voltage regulator system and results are presented and compared with the previous method.

Often real world provides some complex optimization problems that can not be easily dealt with available mathematical optimization methods. If the user is not very conscious about the exact solution of the problem in hand then intelligence emerged from social behavior of social colony members may be used to solve these kind of problems. Based on this concept, Passino proposed an optimization technique known as the bacterial foraging optimization algorithm (BFOA). The foraging behavior of bacteria produces an intelligent social behavior, called as swarm intelligence. Social foraging behavior of Escherichia coli is studied by researchers anti developed a new algorithm named bacterial foraging optimization algorithm (BFOA). BFOA is a widely accepted optimizationalgorithm and currently it is a growing field of research for distributed optimization and control. Since its inception, a lot of research has been carried out to make BFOA more and more efficient and to apply BFOA for different types of problems. This paper presents a review of BFOA modifications and it application areas.

This paper presents a heuristic optimization methodology, namely, bacterialforaging PSO-DE (BPSO-DE) algorithm by integrating bacterial foraging optimization algorithm (BFOA), Particle Swarm optimization (PSO) and Differential Evolution (DE) for solving non-smooth non-convex Dynamic Economic Dispatch (DED) problem. The DED problem exhibits non-smooth, non-convex nature due to valve-point loading effects, ramp rate limits, spinning reserve capacity, prohibited operating zones and security constraints. The proposed hybrid method eliminates the problem of stagnation of solution with the incorporated PSO and DE operators in original bacterialforagingalgorithm. It achieves global cost by selecting the bacterium with good foraging strategies. The bacteria with good foraging strategies are obtained in the updating process of every chemo-tactic step by the PSO operator. The DE operator fine tunes the solution obtained through bacterialforaging and PSO operator. A 3- and 7-unit systems for static economic dispatch, a 26-bus, 6-generator test system and an IEEE 39-bus, 10-unit New England test systems are considered to show the effectiveness of the proposed method over other methods reported in the literature.

Transmission of high density digital information plays an important role in the present age of communication and information technology. These data are distorted while arriving at the receiver end due to inter symbol interference (ISI) in the channel. The adaptive channel equalizer alleviates this distortion and reconstructs the transmitted data faithfully. In recent years the area of bacterialforagingoptimization (BFO) has drawn attention of many researchers due to its broad applicability to different fields. In this paper, the proposed algorithm combines the foraging mechanism of E-coli bacterium introduced in bacterialforagingalgorithm (BFA) with the swarming pattern of birds in block introduced in Particle Swarm optimization (PSO).It incorporates the merits of the two bio-inspired algorithms to update the weights of the equalizer. Simulation study has been carried out to show superior performance of the proposed equalizer compared to that offered by least mean square (LMS) algorithm and genetic algorithm (GA) based training.
