**A maximum entropy algorithm with parameters for solving minimax problem**

Li-Wei Zhang and Huan-Wen Tang(Dalian University of Technology, China) |

*p*has the same optimum which is associated with the minimax problem. A maximum entropy algorithm with parameters is given and its properties are discussed. It is also proved that the optimum of a minimax problem can be obtained by solving a nonlinear system of algebraic equations and this nonlinear system can be solved by the Newton method.
