摘要：This work presents two transformation functions, the a-function and the M-function, for finding better minimizers in global optimization. We prove that under some general assumptions these functions possess the characters of both tunnelling functions and filled functions. Numerical tests from some test functions show that our transformation functions are very effective in finding better minima. (C) 2007 Elsevier Ltd. All rights reserved.
