This book was released on 2019-08-22 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metaheuristic optimization is a higher-level procedure or heuristic designed to find, generate, or select a heuristic (partial search algorithm) that may provide a sufficiently good solution to an optimization problem, especially with incomplete or imperfect information or limited computation capacity. This is usually applied when two or more objectives are to be optimized simultaneously. This book is presented with two major objectives. Firstly, it features chapters by eminent researchers in the field providing the readers about the current status of the subject. Secondly, algorithm-based optimization or advanced optimization techniques, which are applied to mostly non-engineering problems, are applied to engineering problems. This book will also serve as an aid to both research and industry. Usage of these methodologies would enable the improvement in engineering and manufacturing technology and support an organization in this era of low product life cycle. Features: Covers the application of recent and new algorithms Focuses on the development aspects such as including surrogate modeling, parallelization, game theory, and hybridization Presents the advances of engineering applications for both single-objective and multi-objective optimization problems Offers recent developments from a variety of engineering fields Discusses Optimization using Evolutionary Algorithms and Metaheuristics applications in engineering

Download or read book A Brief Introduction to Continuous Evolutionary Optimization written by Oliver Kramer and published by Springer. This book was released on 2013-12-07 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical optimization problems are often hard to solve, in particular when they are black boxes and no further information about the problem is available except via function evaluations. This work introduces a collection of heuristics and algorithms for black box optimization with evolutionary algorithms in continuous solution spaces. The book gives an introduction to evolution strategies and parameter control. Heuristic extensions are presented that allow optimization in constrained, multimodal and multi-objective solution spaces. An adaptive penalty function is introduced for constrained optimization. Meta-models reduce the number of fitness and constraint function calls in expensive optimization problems. The hybridization of evolution strategies with local search allows fast optimization in solution spaces with many local optima. A selection operator based on reference lines in objective space is introduced to optimize multiple conflictive objectives. Evolutionary search is employed for learning kernel parameters of the Nadaraya-Watson estimator and a swarm-based iterative approach is presented for optimizing latent points in dimensionality reduction problems. Experiments on typical benchmark problems as well as numerous figures and diagrams illustrate the behavior of the introduced concepts and methods.

Download or read book An Integrated Evolutionary System for Solving Optimization Problems written by Abu Saleh Shah Muhammad Barkat Ullah and published by . This book was released on 2009 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many real-world decision processes require solving optimization problems which may involve different types of constraints such as inequality and equality constraints. The hurdles in solving these Constrained Optimization Problems (COPs) arise from the challenge of searching a huge variable space in order to locate feasible points with acceptable solution quality. Over the last decades Evolutionary Algorithms (EAs) have brought a tremendous advancement in the area of computer science and optimization with their ability to solve various problems. However, EAs have inherent difficulty in dealing with constraints when solving COPs. This thesis presents a new Agent-based Memetic Algorithm (AMA) for solving COPs, where the agents have the ability to independently select a suitable Life Span Learning Process (LSLP) from a set of LSLPs. Each agent represents a candidate solution of the optimization problem and tries to improve its solution through cooperation with other agents. Evolutionary operators consist of only crossover and one of the self-adaptively selected LSLPs. The performance of the proposed algorithm is tested on benchmark problems, and the experimental results show convincing performance. The quality of individuals in the initial population influences the performance of evolutionary algorithms, especially when the feasible region of the constrained optimization problems is very tiny in comparison to the entire search space. This thesis proposes a method that improves the quality of randomly generated initial solutions by sacrificing very little in diversity of the population. The proposed Search Space Reduction Technique (SSRT) is tested using five different existing EAs, including AMA, by solving a number of state-of-the-art test problems and a real world case problem. The experimental results show SSRT improves the solution quality, and speeds up the performance of the algorithms. The handling of equality constraints has long been a difficult issue for evolutionary optimization methods, although several methods are available in the literature for handling functional constraints. In any optimization problems with equality constraints, to satisfy the condition of feasibility and optimality the solution points must lie on each and every equality constraint. This reduces the size of the feasible space and makes it difficult for EAs to locate feasible and optimal solutions. A new Equality Constraint Handling Technique (ECHT) is presented in this thesis, to enhance the performance of AMA in solving constrained optimization problems with equality constraints. The basic concept is to reach a point on the equality constraint from its current position by the selected individual solution and then explore on the constraint landscape. The technique is used as an agent learning process in AMA. The experimental results confirm the improved performance of the proposed algorithm. This thesis also proposes a Modified Genetic Algorithm (MGA) for solving COPs with equality constraints. After achieving inspiring performance in AMA when dealing with equality constraints, the new technique is used in the design of MGA. The experimental results show that the proposed algorithm overcomes the limitations of GA in solving COPs with equality constraints, and provides good quality solutions.

Download or read book Evolutionary Approach for Constrained Optimization written by Saber Elsayed and published by . This book was released on 2012 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constrained optimization is a challenging area of research in the science and engineering disciplines. Locating the optimal solutions for such problems is often difficult as their characteristics and mathematical properties do not follow any standard patterns or forms. Over the last few decades, evolutionary algorithms (EAs) have been widely used for solving optimization problems. Although there are many EAs for solving Constrained Optimization Problems (COPs), no single algorithm performs consistently over a wide range of problems. Therefore, ideas for multi-operator- and multi-methodology-based algorithms have recently been introduced but their actual strengths for solving COPs have not been fully explored. The choice of operators and/or algorithms and their appropriate mix, and a strategy for their use in designing an effective EA have not been well studied. In this thesis, a general framework for solving COPs that allows the use of different operators and/or algorithms under a single algorithmic structure is proposed and a good number of algorithms are designed, implemented, analyzed and tested. In this research, firstly, multi-operator EAs are studied. They can be implemented in many different ways, such as with and without population divisions, adaptations and local searches, and offer different ways of choosing and mixing operators. To test the robustness of this concept, two different EAs, known as the genetic algorithm (GA) and differential evolution (DE), are considered. Different variants of a multi-operator GA and multioperator DE are implemented with and without self-adaptation, population changes and local searches. The purpose of introducing self-adaptation is for the appropriate mix of operators to be automatically chosen with the progress of evolution. To do this, a new self-adaptive mechanism is derived and its number and choice of operators are discussed and justified. Initially, one type of operator, a crossover for GA and a mutation for DE, is considered. Later, these algorithms are extended to include multiple crossover and mutation operators and designed to use a self-adaptive mechanism to change the number of individuals assigned to each. The DE-based algorithm is further extended to include different constraint-handling techniques (CHTs). In its implementation, each chromosome contains information on the use of a single crossover, a single mutation and a single CHT. To accelerate the performances of these algorithms, a local search technique is also applied. The framework proposed for an EA with multiple operators is further extended to include multiple EAs under a single algorithmic framework. Therefore, a new algorithm, in which the population is divided into sub-populations, where each subpopulation runs a defined multi-operator EA, is introduced. The number of EAs used are discussed and analyzed. To demonstrate consistent performances of all the proposed algorithms, they solve the problems from two different specialized sets of benchmark problems and a detailed parametric analysis of them is provided. For comparisons of the competing algorithms, a new comparison matrix is introduced. The results from this thesis can be summarized as follows: (1) the multi-operator based GA is able to obtain much better solutions than those of each independent GA with a single operator; (2) the use of the self-adaptive mechanism leads to much better solutions and savings in time; (3) the multi-operator based GA is competitive with the state-of-the-art algorithms; (4) the self-adaptive multioperator-based DE is not only better than the single operator-based DE but also takes 25% less computational time than a standard DE; (5) the self-adaptive multi-operatorbased DE with a local search technique performs much better and takes 48% less computational than the algorithm without a local search; (6) the self-adaptive DE with a mix of crossover and mutation operators plus a local search is better than those without a local search and is also superior to the state-of-the-art algorithms; (7) DE with multiple crossover and mutation operators plus CHTs is able to obtain better solutions than DE with a single operator and different state-of-the-art algorithms; (8) the multimethodology EA with three different algorithms performs best, is superior to DE with a multiple mutation operators the state-of-the-art algorithms and consumes 26% less computational time than the self-adaptive multi-operator DE; and (9) considering all the algorithms implemented and tested in this thesis, the memetic self-adaptive multioperator DE is the best.
