Several algorithms inspired in recent years by the swarm behavior of honeybees have been developed for a variety of practical applications. The bees algorithm (BA) is one of these swarm-based algorithms that imitate the intelligent behaviors of honeybees. The present paper proposes a Novel bees algorithm (NBA) that uses a stochastic self-adaptive neighborhood (ssngh) search to improve the original BA. The ssngh automatically and dynamically reflects swarm convergence conditions and frees its settings. Additionally, this paper tests two additional designs for bee relocation as well as the effect on algorithm performance of using fewer recruited bees. Experimental results are compared using 23 benchmark functions. Results demonstrate that the proposed NBA not only frees the parameter settings of the neighborhood ranges of BA but also significantly improves upon the convergence performance of the original BA. Additionally, experimental results indicate that the NBA outperforms the artificial bee colony (ABC) algorithm on 12 benchmark functions, while the ABC outperforms the NBA on only 8 benchmark functions.

Microbial strain optimization focuses on improving technological properties of the strain of microorganisms. However, the complexities of the metabolic networks, which lead to data ambiguity, often cause genetic modification on the desirable phenotypes difficult to predict. Furthermore, vast number of reactions in cellular metabolism lead to the combinatorial problem in obtaining optimal gene deletion strategy. Consequently, the computation time increases exponentially with the increase in the size of the problem. Hence, we propose an extension of a hybrid of bees algorithm and Flux Balance Analysis (BAFBA) by integrating OptKnock into BAFBA to validate the result. This paper presents a number of computational experiments to test on the performance and capability of BAFBA. Escherichia coli, Bacillus subtilis and Clostridium thermocellum are the model organisms in this paper. Also included is the identification of potential reactions to improve the production of succinic acid, lactic acid and ethanol, plus the discussion on the changes in the flux distribution of the predicted mutants. BAFBA shows potential in suggesting the non-intuitive gene knockout strategies and a low variability among the several runs. The results show that BAFBA is suitable, reliable and applicable in predicting optimal gene knockout strategy.

The bees algorithm (BA) is a population-based metaheuristic algorithm inspired by the foraging behavior of honeybees. This algorithm has been successfully used as an optimization tool in combinatorial and functional optimization fields. In addition, its behavior very closely mimics the actual behavior that occurs in nature, and it is very simple and easy to implement. However, its convergence speed to the optimal solution still needs further improvement and it also needs a mechanism to obviate getting trapped in local optima. In this paper, a novel initialization algorithm based on the patch concept and Levy flight distribution is proposed to initialize the population of bees in BA. Consequently, we incorporate this initialization procedure into a proposed enhanced BA variant. The proposed variant is more natural than conventional variants of BA. It mimics the patch environment in nature and Levy flight, which is believed to characterize the foraging patterns of bees in nature. The results of experiments conducted on several widely used high-dimensional benchmarks indicate that our proposed enhanced BA variant significantly outperforms other BA variants and state-of-the-art variants of the Artificial Bee Colony (ABC) algorithm in terms of solution quality, convergence speed, and success rate. In addition, the results of experimental analyses conducted indicate that our proposed enhanced BA is very stable, has the ability to deal with differences in search ranges, and rapidly converges without getting stuck in local optima.

Integrating the artificial bee colony and bees algorithm to face constrained optimization problems

Swarm intelligence (SI) has generated growing interest in recent decades as an algorithm replicating biological and other natural systems. Several SI algorithms have been developed that replicate the behavior of honeybees. This study integrates two of these, the artificial bee colony (ABC) and bees algorithms (BA), into a hybrid ABC-BA algorithm. In ABC-BA, an agent can perform as an ABC agent in the ABC sub-swarm and/or a BA agent in the BA sub-swarm. Therefore, the ABC and BA formulations coexist within ABC-BA. Moreover, the population sizes of the ABC and BA sub-swarms vary stochastically based on the current best fitness values obtained by the sub-swarms. This paper conducts experiments on six constrained optimization problems (COPs) with equality or inequality constraints. In addressing equality constraints, this paper proposes using these constraints to determine function variables rather than directly converting them into inequality constraints, an approach that perfectly satisfies the equality constraints. Experimental results demonstrate that the performance of the ABC-BA approximates or exceeds the winner of either ABC or BA. Therefore, the ABC-BA is recommended as an alternative to ABC and BA for handling COPs. (C) 2013 Elsevier Inc. All rights reserved.

This study presents the successful application of the bees algorithm (BA) for optimal design of a cross- flow plate fin heat exchanger by offset strip fins. The epsilon - NTU method is used to approximate the heat exchanger effectiveness and pressure drop. Two different objective functions including the minimization of total annual cost (sum of investment and operational costs) and total number of entropy generation units for certain heat duty required under given space constraints are considered as targets of optimization separately. Based on the applications, seven design parameters (heat exchanger length at hot and cold sides, fin height, fin frequency, fin thickness, fin-strip length, and number of hot side layers) are selected as optimization variables. Two examples from the literature are presented to illustrate the efficiency and accuracy of the proposed algorithm. Results showed that the BA can detect an optimum configuration with higher speed (short computational time) and accuracy compared to the imperialist competitive algorithm (ICA) and the genetic algorithm (GA).

In this study, the single-objective and multi-objective optimizations of composite laminates with free-edge boundaries are presented. bees algorithm (BA) is used to search for the optimal design. An analytical technique is utilized to calculate the edge effect stresses at the free boundaries of the laminates. For this purpose, two laminates are considered: a flawless laminate with free straight edges and a laminate with a hole. The two laminates are subjected to uni-axial and thermal loads. The design of optimal layup in single-objective optimization is based on maximizing the interlaminar strength of the laminates. The multi-objective optimization is formulated for maximizing the interlaminar strength, minimizing the weight and the total cost of the composite components. The optimization variables are considered to be the number of layers, stacking sequence, and the thickness of each layer. Moreover, to verify the performance of BA, the results are compared with those of particle swarm optimization (PSO) and those based on resulting from multi-objective optimization of Kursave (KUR) function. The results of this study show the effect of geometric conditions of free edges as well as the type of loading (mechanical and thermal) on the optimization of composite laminates.

Electric machines designs for traction application are concerned with paying particular attention to power density and efficiency. Therefore, this paper is focused on applying bees algorithm (BA) for optimal design of Brushless Permanent Magnet Synchronous Motor (BLPMSM) for propulsion application. The analytical approach for the motor magnetic circuit is performed using the radial instantaneous magnetic field distribution in the airgap under specified loading condition;taking into account the magnetic core saturation and motor overall performance. The design aims to maximize the power density. Therefore, the optimisation objective function is formed to minimise motor weight and maximise efficiency. While the bees algorithm (BA) is applied to search for the optimum design parameters;the optimised design is then verified using Finite Element Method (FEM). Comparing with an existing machine, called here basic motor;the obtained results show that motor weight can be reduced by approximately 20%, while motor output power is kept constant. As the motor is designed for traction applications, the characteristics of the developed torque and speed were investigated under different gearing levels using magnetic gearing technique, the efficiency shows improvements in comparison to the basic motor.

Remanufacturing represents one of the most promising strategies for promoting circular economy (CE) principles and achieving economic and environmental sustainability goals. The implementation of Industry 4.0 (I4.0) enabling technologies such as cloud computing and the Internet of Things in the classical remanufacturing process provides the opportunity to define a new approach called Cloud Remanufacturing, which realises a distributed system in which remanufacturing resources, located at different geographic sites, are shared and managed in a centralised environment. This paper aims to introduce the new concept of Cloud Remanufacturing by proposing a framework to explain its logic and characterise its main features. Furthermore, the mathematical relationships for evaluating the costs and the times for completing the remanufacturing process enhanced by I4.0 technologies will be developed, and, relying on them, the model will be tested for 2 scenarios involving different extended areas. In detail, the problem of activity scheduling in Cloud Remanufacturing will be addressed using two metaheuristic approaches. The results show the effectiveness and theoretical applicability of the model, even if a comparison with a real case study is not possible due to the lack of a real centrally managed remanufacturing distributed system.

The subject of the paper is the application of metaheuristic algorithms inspired by nature for multi-criteria optimization in new generation optical networks. In the considered optical network, criteria related to the structure and topology of the network and the equipment used were taken into account. Network criteria include the length of optical channels, optical fiber attenuation, and dispersion. On the other hand, the hardware criteria include the cost of transponders and a finite range of frequency slides in the optical spectrum of the optical fiber. Several nature-inspired metaheuristics were used for the multi-criteria optical network optimization problem. The proposed algorithm, based on the bee algorithm was compared with others taken from the literature. Simulation results of all algorithms were implemented and carried out using test networks with topology typical for telecommunication networks. The proposed and improved algorithm obtained good results that encourage further work and research.

Deep Learning (DL) is a type of machine learning used to model big data to extract complex relationship as it has the advantage of automatic feature extraction. This paper presents a review on DL showing all its network topologies along with their advantages, limitations, and applications. The most popular Deep Neural Network (DNN) is called a Convolutional Neural Network (CNN), the review found that the most important issue is designing better CNN topology, which needs to be addressed to improve CNN performance further. This paper addresses this problem by proposing a novel nature inspired hybrid algorithm that combines the bees algorithm (BA), which is known to mimic the behavior of honey bees, with Bayesian Optimization (BO) in order to increase the overall performance of CNN, which is referred to as BA-BO-CNN. Applying the hybrid algorithm on Cifar10DataDir benchmark image data yielded an increase in the validation accuracy from 80.72% to 82.22%, while applying it on digits datasets showed the same accuracy as the existing original CNN and BO-CNN, but with an improvement in the computational time by 3 min and 12 s reduction, and finally applying it on concrete cracks images produced almost similar results to existing algorithms.
