Memetic Algorithm (MA) is a population based heuristic search approach for optimization problems similar to genetic algorithm. GAs, however, rely on the concept of biological evolution, but MAs, in contrast, and mimic cultural evolution. The cryptanalysis of simplified data encryption standard can be formulated as NP-hard combinatorial problem. In this paper, a comparison between memetic algorithm and Tabu search were made in order to investigate the performance for the cryptanalysis on Simplified Data Encryption Standard problems (SDES).
