چکیده
Anthony Pioli April 4, 1997 When we hear the terms \genetic" and \algorithm", we normally would not concatenate the two together. This paper describes \genetic algorithms" and hopefully shows that the two terms can be used together. In the rst part, I explain what genetic algorithms are and how they work. In the second section, some examples are shown, and nally some concluding remarks are made. 1 What is a Genetic Algorithm? A genetic algorithm is a search algorithm. It 'evolves' a set of possible solutions until a satisfactory one is found. The basic idea is that a particular solution will pass its informational content onto its successors if it is a 'good' solution. The better the solution is, the higher is the probability of passing on its information; survival of the ttest in other words. In Fig. 1 I have shown a simple function, f(x). This particular function has a domain of all integers from 0 to 255 and a range of [0.0,1.0]. 1.0

A New Approach to Solve N-Queen Problem with Parallel Genetic Algorithm
Over the past few decades great efforts were made to solve uncertain hybrid optimization problems. The n-Queen problem is one of such problems that many solutions have been proposed for. The traditional methods to solve this problem are exponential in terms of runtime and are not acceptable in terms of space and memory complexity. In this study, parallel genetic algorithms are proposed to solve...

متن کاملSolving random inverse heat conduction problems using PSO and genetic algorithms
The main purpose of this paper is to solve an inverse random differential equation problem using evolutionary algorithms. Particle Swarm Algorithm and Genetic Algorithm are two algorithms that are used in this paper. In this paper, we solve the inverse problem by solving the inverse random differential equation using Crank-Nicholson's method. Then, using the particle swarm optimization algorith...

متن کاملSolving a Stochastic Cellular Manufacturing Model by Using Genetic Algorithms
This paper presents a mathematical model for designing cellular manufacturing systems (CMSs) solved by genetic algorithms. This model assumes a dynamic production, a stochastic demand, routing flexibility, and machine flexibility. CMS is an application of group technology (GT) for clustering parts and machines by means of their operational and / or apparent form similarity in different aspects ...
متن کاملStaff Scheduling by a Genetic Algorithm
This paper describes a Genetic Algorithms approach to amanpower-scheduling problem arising at a Petrochemical Company. AlthoughGenetic Algorithms have been successfully used for similar problemsin the past, they always had to overcome the limitations of theclassical Genetic Algorithms paradigm in handling the conflict betweenobjectives and constraints. The approach taken here is to use an indir...
