Optimization Design Based on Improved Ant Colony Algorithm

For the structural optimization design problems, a pseudo-parallel ant colony algorithm was introduced based on binary and a graph-based ant system. With the improved ant colony algorithm, the pseudo-parallel ant colony algorithm was applied to the soluation of structural optimization parameters successfully. Practical examples showes that the improved ant colony algorithm can solve continuous optimization problem with a faster convergence speed and a better precision in calculation, and it can be used on engineering optimization design.
