Abstract: A filled function is proposed based on the objective function and the square of the distance between variate and extremum point. With the filled function, from a minimum point we can find another minimum point at which the value of the function is less than the former value. We have proven it can make the function reach to the global minimum but not maximum or saddle point value to select r properly. Finally steps and examples of the algorithm are given.

Key words: filled function, basin, minimum
