Abstract:An improved Character-base Ant Colony Algorithm based on Character-base Ant Colony Algorithm and sentience consciousness characters is presented in this paper. It can significantly prevent precocity, then make a balance between accelerating convergence and averting precocity as well as stagnation. The algorithm is applied to clustering analysis and the algorithm steps of the model have been designed to illustrate the performance of the algorithm in this paper. The results of simulation on clustering analysis indicate that the new algorithm is feasible and effective.
