A Simulated Annealing Algorithm for The Capacitated Vehicle Routing Problem H. Harmanani, D. Azar, N. Helal Department of Computer Science & Mathematics Lebanese American University Byblos, 1401 2010, Lebanon Abstract The Capacitated Vehicle Routing Problem (CVRP) is a combinatorial optimization problem where a fleet of delivery vehicles must service known customer demands from a common depot We propose a Population based dual-sequence Non-Penalty Annealing algorithm (PNPA) for solving the general nonlinear constrained optimization problem. The PNPA maintains a population of solutions that are intermixed by crossover to supply a new starting solution for simulated annealing throughout the search. However, for some case problems, the method may have some dif®culty in locating a feasible solution (Michalewicz, 1995). 7. Solving BSP using genetic algorithms Two types of genetic algorithms were tested, for each of the methods discussed in the previous section: a simple genetic algorithm (SGA) and a real coded genetic algorithm (RGA). Genetic algorithm (GA) and simulated annealing (SA) have been applied to many difficult combinatorial optimisation problems with certain strengths and weaknesses. In this paper, genetic simulated annealing (GSA), which is a hybrid of GA and SA, is used to determine optimal machining parameters for milling operations.

Genetic algorithms • A candidate solution is called anindividual – In a traveling salesman problem, an individual is a tour • Each individual has a fitness: numerical value proportional to the evaluation function • A set of individuals is called apopulation • Populations change over generations,byapplyingoperations to the constraints are classified as hard and soft constraints. use two different methods, namely, Simulated Annealing and Genetic Algorithm to solve this problem and compared their performances at different difficulty levels. Index Terms— constraints, genetic algorithm, nurse the construction of duty rosters for nursing staff over a pre tend to become more common as the search space increases in size. Genetic algorithm and simulated annealing give an excellent trade-off between solution quality and computing time and flexibility for taking into account specific constraints in real situations. Simulated annealing is a search process that has The goal of this study of threshold acceptance algorithm (TA), simulated annealing algorithm (SA) and genetic algorithm (GA) is to determine strength of Genetic Algorithm over other algorithm. It gives a clear idea of how genetic algorithm works. It gives the idea of various sub methods used in genetic algorithm to improve the results and outcome. constraints using evolutionary algorithm which is essential for a firm to survive in today’s the annealing and genetic algorithm approaches of similar problems when the graph may change As the algorithm climbs over the better solution to reach the peak, it may not be suitable for bin packing optimization In computer science and operations research, a genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on bio-inspired operators such as mutation, crossover and selection.
