For example, there are three parameters w, c 1, and c 2 that should be determined in updating equations of PSO. Moreover, the optimal parameters of the algorithms are often difficult to be determined. To decrease the effects of parameters for the algorithms, teaching-learning-based TLBO algorithm [ 15 ] is proposed recently, and it has been used in some real applications [ 16 — 19 ].
Under the framework of population-based optimizations, many variations of evolutionary optimization algorithms have been designed. Each of these algorithms performs well in certain cases and none of them are dominating one another.
The key reason for employing the hybridization is that the hybrid algorithm can take advantage of the strengths of each individual technique while simultaneously overcoming its main limitations. On top of this idea, many hybrid algorithms have been presented [ 22 — 27 ].
In the improved TLBO algorithm, the teacher improves not only the performance of the mean grade of the whole class but also the performance of every student. The proposed algorithm has been evaluated on some benchmark functions, and the results are compared with some other algorithms.
The paper is organized as follows. Section 2 provides a brief description of the standard PSO algorithm.
Some experiments are given in Section 5. Section 6 concludes the paper. State true T or false F i Service rate describes the number of customers serviced during a particular time period. The Branching is the simple operation that divides a program into two subproblems, such that the solution of the original problem can be found from the solutions of the main problems.
The bounding operation is a function that returns a bound on the optimal solution of the current subproblem. State true T or false F Some of the main ideas of Branch and Bound technique is i If the relaxed problem is infeasible-backtrack. A game with two players, where a gain of one player equals the loss to the other is known as a two-person zero-sum game.
A payoff is a rule strictly followed when playing a game. State true T or false F Characteristic of a Two-person-zero-sum game is i Only two players participate ii Each specific strategy results in a payoff. Standard error is volatile ii. A simulation model involves several variables. The OR approach to problem solving consists of the following steps 1. Definition of the problem 2. Preface This book is addressed to students in fields of engineering and technology as well as practicing engineers.
It covers the fundamentals of commonly used optimization methods used in engineering design.
Optimization methods fall among the mathematical tools typically used to solve engineering problems. It is therefore desirable that graduating students and practicing engineers are equipped with these tools and are trained to apply them to specific problems encountered in engineering practice.
Optimization is an integral part of the engineering design process. It focuses on discovering optimum solutions to a design problem through systematic consideration of alternatives, while satisfying resource and cost constraints.
Many engineering problems are open-ended and complex. The overall design objective in these problems may be to minimize cost, to maximize profit, to streamline production, to increase process efficiency, etc.
Finding an optimum solution requires a careful consideration of several alternatives that are often compared on multiple criteria. Mathematically, the engineering design optimization problem is formulated by identifying a cost function of several optimization variables whose optimal combination results in the minimal cost.
