Abstract:

An improved ant colony algorithm is developed based on TACO. MAXMIN ant system is introduced. A new method of positiverealnumber coding is put forward for enlarging search range and simplifying search process. In order to reduce the influence of the evaporation coefficients, the most and least value of pheromone and the value of optimized function, a new technology of constantpheromone update is put forward. Thus the algorithmic performance and universality are improved.

Key words: structural , optimization, shape , optimization, ant , colony , algorithm, TACO, FEM
