Abstract

Abstract The increase in the size of universities has greatly increased the number of teachers, students, and courses and has also increased the difficulty of scheduling courses. This study used coevolution to improve the genetic algorithm and applied it to solve the course scheduling problem in universities. Finally, simulation experiments were conducted on the traditional and improved genetic algorithms in MATLAB software. The results showed that the improved genetic algorithm converged faster and produced better solutions than the traditional genetic algorithm under the same crossover and mutation probability. As the mutation probability in the algorithm increased, the fitness values of both genetic algorithms gradually decreased, and the computation time increased. With the increase in crossover probability in the algorithm, the fitness value of the two genetic algorithms increased first and then decreased, and the computational time decreased first and then increased.
基于改进遗传算法的高校排课问题优化解
高校规模的扩大,大大增加了教师、学生和课程的数量,也增加了排课的难度。本研究利用协同进化对遗传算法进行改进,并将其应用于解决高校课程调度问题。最后,在MATLAB软件中对传统遗传算法和改进遗传算法进行了仿真实验。结果表明,在相同的交叉概率和变异概率下,改进的遗传算法比传统遗传算法收敛速度更快,求解结果更好。随着算法中突变概率的增加,两种遗传算法的适应度值逐渐降低,计算时间增加。随着算法中交叉概率的增加,两种遗传算法的适应度值先增大后减小,计算时间先减小后增大。
