| Abstract: | 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. |
| Keywords: | distributed communication system optimization problem interior point method preconditioner numerical stability |
