The Memetic algorithms (MA) are computational models inspired by the Cultural Revolution. Robustness, scalability and simplicity are the advantages of Memetic algorithms. By looking at this strength of MA, they are very much suitable for solving some combinatorial optimization problems which falls in the category of NP-hard problems. In this paper, we propose MA based optimization model for Dynamic Traveling Salesman Problem (DTSP), to achieve overall higher system performance and better throughput.During implementation, results are obtained with number of randomly generated Traveling Salesman Problem instances, measured in terms of required time, quality and path length. It has been observed that the proposed model works well in terms of quality and path length. As it uses Simulated Annealing, it is found little bit less effective in terms of time.

Ant Colony Optimization (ACO) is a novel and competitive optimization method for numerous combinatorial optimization problems. It is already applied to various optimization problems. Normally it proved best in terms of solution quality, accuracy and other parameters. This paper presents an Elitist Ant System (EAS) which uses tuning in pheromone update process to improve the performance of the basic Ant System (AS) approach. Dynamic Traveling Salesman Problem is solved in this research with the various pheromone update strategy for finding the improvements in the results. The results obtained are empirically compared with the results obtained with the basic pheromone update strategy of Ant System.Keywords
