By J. Joshua Thomas, Ahamad Tajudin Khader, Bahari Belaton, Eben Christy
Issue Date:August 2010
pp. 167-172
NP-Hard problems are hard to solve, it requires considerable computational power to generate solutions. The objective is to achieve better solution in less time. To obtain better solutions in semi-automated examination timetabling systems, we introduce vis...
 
A parameter-less genetic algorithm with customized crossover and mutation operators
Found in: Proceedings of the 13th annual conference on Genetic and evolutionary computation (GECCO '11)
By Ahamad Tajudin Khader, Farhad Nadi
Issue Date:July 2011
pp. 901-908
Genetic algorithm is one of the well-known population based meta-heuristics. The reasonable performance of the algorithm on a wide variety of problems as well as its simplicity made this algorithm a first choice in lots of cases. However, the algorithm has...
