摘要
为了优化移动互联网的分布式通信系统的响应速度,建立分布式通信系统响应速度最优化问题的数学模型,并设计和改进求解该最优化问题的内点法.针对该最优化问题发展一套高效率预条件方法来帮助求解内点法,不但改善计算方法的数值稳定性,而且提高算法的计算效率.通过数值实验验证该预条件对算法稳定性和效率的提高.
To optimize the responsiveness of distributed communication system on mobile Internet, a mathematical model of system responsiveness optimization is established, and a solver based on interior method is designed. To improve the numerical stability and efficiency of the solver, a fast preconditioner is developed. Numerical experiments are carried out to verify the stability and efficiency of the solver due to the preconditioner.
