This paper presents a speed control of Direct Current (DC) motor with a Proportional-Integral-Derivative (PID) controller optimized by a new metaheuristic algorithm. A novel metaheuristic optimization method is proposed in this paper based on an earthquake as geology phenomenon. The Earthquake algorithm (EA) is used to optimize both plant model and PID controller. Experimental results show a feasibility of the proposed method improving both the plant model and speed controller by PID. Besides, the implemented experimental control system proves that EA works in all different continuous nonlinear functions or engineering applications.

We propose the metaheuristic algorithm to solve the The Resource-Constrained Project Scheduling Problem (RCPSP). The approach method extends the Particle Swarm Optimization (PSO) by regrouping the agent particles within the appropriate radius of the circle. It initializes the group of particles, calculates the fitness function, and finds the best particle in that group. Then, it incorporates the adaptive mutation and forward-backward improvement to hybridize local search algorithm for constructing the feasible project scheduling with the minimal make-span. The efficiency of the proposed method is tested against the well-known benchmarks. The results show that the proposed method gives better optimum rate and standard deviation than some existing procedures.

The home appliance scheduling (HAS) problem is a critical issue in the home energy management system (HEMS). The aim of the HAS is to control the appliances at home more efficiently and economically. However, there is still plenty room for improvement because the home appliances scheduling problem is a challenging issue due to its complexity. Many researchers have proposed schemes to solve this problem, but most of the results are either unsatisfied or taking too much computation effort but with limited performance improvement. In this paper, we propose a novel metaheuristic algorithm called search economics for home appliances scheduling (SEHAS) to address this issue more efficiently. SEHAS approach is based on search economies (SE). We first formulate the the HAS problem as a knapsack problem, and then we define our objectives as minimization of the electricity cost. We then present the proposed SEHAS in details to show how it can solve the scheduling problem efficiently. To better evaluate our proposed scheme, we conduct simulations to compare results with two classical metaheuristic algorithm, including genetic algorithm (GA) and ant colony optimization (ACO) algorithms. The experimental results show that when compared to the scenario without any scheduling algorithm that GA and ACO can reduce the electricity cost 17.60% and 18.05% respectively, and the proposed metaheuristic algorithm SEHAS can save the cost up to 19.29%. In addition, GA, ACO and SEHAS can reduce peak-to-average ratio (PAR) 13.53%, 24.01% and 24.01% respectively.

In this paper a Logistics transportation problem including routing, scheduling and loading tasks is presented. Most of the related works only involve the solution of routing and scheduling, as a combination of up to six different types of VRPs (Rich VRP), leaving away the loading task, which are not enough to define more complex real-world cases. We propose a solution methodology for transportation instances that involve six types of VRPs, a new constraint that limits the number of vehicles that can be attended simultaneously and the loading tasks. They are solved using an Ant Colony System algorithm, which is a hybrid metaheuristic. Results from a computational test using real-world instances show that the proposed approach outperforms the transportation planning related to manual designs. Besides a well-known VRP benchmark was solved to validate the approach.

The multi-depot vehicle routing problem with time windows (MDVRPTW) is an extension to the classical Vehicle Routing Problem (VRP);it is the major research topics in the supply chain management field. It aims to designing a set of minimum-cost routes for a vehicle fleet servicing many customers with known demands and predefined time windows. In this paper a hybrid metaheuristic algorithm is proposed to solve MDVSPTW successfully by ants transfer policy and algorithm to construct solution designed in this dissertation. To improve hybrid ant colony algorithm performance, a local search improvement algorithm that explores a large neighborhood of the current solution to discover a cheaper set of feasible routes. The neighborhood structure comprises all solutions that can be generated by iteratively performing node exchanges among nearby trips followed by a node reordering on every route. The experiment indicates the validity of the technique to MDVSPTW with the above-mentioned conditions.

Intrusion detection system (IDS) is typically used to detect and prevent abnormal behaviors in a network management system. The basic idea of IDS is to use feature values from network packet capture mechanism to classify whether a behavior is abnormal. However, most traditional classification algorithms are incapable of recognizing unknown behaviors. To develop a high performance classification algorithm to improve the accuracy of IDS, the algorithm proposed in this paper will integrate clustering, classification, and metaheuristic algorithms as a classification algorithm for IDS, called search economics with k-means and support vector machine (SEKS). Moreover, this hybrid strategy for the proposed algorithm is aimed at improving the accuracy of abnormal behavior detection of such a system, reducing the computation time of a classification algorithm, and making it possible for the IDS to recognize the unknown and new variant attacks in a network environment. The experimental results show that the proposed algorithm outperforms all the other classification algorithms compared in this paper in terms of the accuracy.

For the safe and accurate operation of lithium-ion battery, the estimation of inner states of battery is necessary. Among many models of battery, electrochemical model, especially P2D model, represents the real dynamics such as transport and diffusion phenomena of charges and lithium-ions. For this reason, P2D model is an appropriate model for estimating the states. In this paper, metaheuristic algorithm is applied to estimate these parameter values, since it is more useful to implement the metaheuristic method than other jacobian-based methods, if the number of the parameters to be estimated is increased. Harmony search is one of the metaheuristic algorithms, and improved harmony search was developed for high convergence rate and fine-tunning. The cascaded version of improved harmony search is proposed as the estimation algorithm in this paper, and it is the first time to using the harmony search for lithium-ion battery parameterization. As a result, the parameters had reasonable values compared to reference values and lower voltage, temperature errors compared to the results of improved harmony search which is employed as a benchmark.

This study proposes a generally applicable improvement strategy for metaheuristic algorithms, improving the algorithm's accuracy and local convergence in finite element (FE) model updating. Based on the idea of "survival of the fittest" in biological evolution, the improvement strategy introduces random crossover and mutation operators into metaheuristic algorithms to improve the accuracy and stability of the solution. The effectiveness of the improvement strategy with three typical metaheuristic algorithms was comprehensively tested by benchmark functions and numerical simulations of a space truss structure. Meanwhile, the initial FE model of a railway hybrid girder cable-stayed bridge was updated to examine the effect of the improved metaheuristic algorithm within the FE model, updating for complex engineering structures. The results show that the accuracy and stability of the improved metaheuristic algorithm were improved by this process. After the initial FE model of the hybrid girder cable-stayed bridge was updated, the calculated frequencies and displacements were closer to the measured values, better representing the actual structure, and showing that this process can be used for baseline FE models of bridges.

metaheuristic algorithms are an important area of research that provides significant advances in solving complex optimization problems within acceptable time periods. Since the performances of these algorithms vary for different types of problems, many studies have been and need to be done to propose different metaheuristic algorithms. In this article, a new metaheuristic algorithm called flood algorithm (FA) is proposed for optimization problems. It is inspired by the flow of flood water on the earth's surface. The proposed algorithm is tested both on benchmark functions and on a real-world problem of preparing an exam seating plan, and the results are compared with different metaheuristic algorithms. The comparison results show that the proposed algorithm has competitive performance with other metaheuristic algorithms used in the comparison in terms of solution accuracy and time.

Quantum light sources in the mid-infrared (MIR) band play an important role in many applications, such as quantum sensing, quantum imaging, and quantum communication. However, there is still a lack of high-quality quantum light sources in the MIR band, such as the spectrally pure single-photon source. In this work, the generation of a spectrally-pure state in an optimized poled lithium niobate crystal using a metaheuristic algorithm is presented. In particular, the particle swarm optimization algorithm is adopted to optimize the duty cycle of the poling period of the lithium niobate crystal. With this approach, the spectral purity can be improved from 0.820 to 0.998 under the third group-velocity-matched condition, and the wavelength-tunable range from 3.0 to 4.0 mu m for the degenerate case and 3.0 to 3.7 mu m for the nondegenerate case. This work paves the way for developing quantum photonic technologies at the MIR wavelength band.
