The correctness of the 0-1 algorithm is verified. It is illustrated that the result of optimization using the algorithm is better than using genetic algorithm, with similar convergence speed. In addition, this algorithm has the advantage that its convergence is quicker than the Integer Linear Programming (ILP) approach.
