《线性代数》课程与Mathematica软件相结合教学的研究

《线性代数》是高等财经本科院校所开设的一门重要基础必修课,学生学习该课程时,在计算方面存在着困难,教学过程中结合使用Mathematica软件不但可以解决计算量大而复杂的问题．而且可以利用软件得到的结果来检验手工算法的准确性,从而达到提高教学质量的目的;另外,可以让学生初步掌握Mathematica软件的使用。

Problem of Flexible Job-Shop Scheduling Based on Improved Genetic Algorithm

Based on the analysis of the traits of flexible job-shop scheduling problem, proposes an improved genetic algorithm to minimize the makespan. Adopts a new initialization method to improve the quality of the initial population and accelerate the speed of the algorithm/s convergence. Consides the characteristic of the problem, reasonable chromosome encoding, gives crossover and mutation operator, and proves the effectiveness of the improved algorithm is by testing.
