A modified combination of artificial immune system and genetic algorithm for optimization problems
Abstract:
Scheduling is one of the most important tasks encountered in real life situations. Various scheduling problems exist, such as, personnel, production and education time tables etc. Educational time table scheduling is a difficult task because of the many constraints that need to be satisfied in order to get a feasible solution. The education time table scheduling problem is known to be a NP-complete problem. The Genetic Algorithm (GA) is based on the biological mechanism of natural selection and heredity, leveraging colony searching technology, and is particularly applicable for the resolution of complicated on-linear problems intractable with traditional searching methods. In this research, the author has further solved the problem with a mimetic hybrid algorithm based on the Artificial Immune System (AIS), and then compared the result with that obtained from GA. The proposed guided mutation operator helps with convergence as a result of the increased constraint satisfaction rates and hence better fitness values.
