摘　　要：提出一个求解连续全局优化的T-F函数,先给出了T-F函数的定义,然后根据提出的T-F函数的性质,设计了一个新的T-F函数算法,并进行数值实验,数值实验的结果表明该算法是有效和可行的。A new T-F function for solving continuous general global minimization problems is introduced. A T- F function is constructed at a local minimizer of the objective function such that it achieves local maximum at the current solution. Moreover, a local minimizer of the T-F function leads to a new solution to the original problem with lower objective function value. Iteration follows in this manner to reach a global minimizer. Promising compu- tational results are included and show the efficiency of the T-F function method.
