Based on the introduction of the basic principle and mathematical model, a novel approach to the convergence proof that applies directly to the ant colony algorithm is proposed in this paper. Then, a MATLAB GUI- based ant colony algorithm simulation platform is developed, and the interface of this simulation platform is very friendly, easy to use and to modify.展开更多

The development of vocational education, after being elevated to the level of national strategy, will inevitably imply that the existing resources for vocational education must be effectively integrated. To improve the quality of vocational educational institutions, enhance social service levels of vocational institutions and provide smooth career paths for professional talents, are the main goal of vocational education in the future. Since innovative education system for vocational institutions is the inevitabl choice to achieve the above development goal, to innovate the educational system by way of cooperative building of vocational education platforms is the inevitable requirement upon the development of vocational education.展开更多
