A Composite Algorithm and Program-MDCP for MixedDiscrete Variable

An new optimimzation algorithm and program of mixed discrete variables are described in this paper. This program applied to solve the optimal problems that involves all or some discrete, integer and continuous variables, and give normalized optimal solution in keeping with engineering requirements.
This algorithm and program has stood the test of 30 problems of engineering design and mathematics. Tne results indicate that the composite algorithm and program have, with some of different reseach function in superior both in reliabilty and efficiency. The reliablity of soultion is 100% according to accuracy under 0.001 of objective function vaule.
Two examples used in mechanical engieering are given.
