Abstract: A general convexification method via domain transformation scheme is presented for solving a class of global optimization problems with certain monotone properties. It is shown that this class of problems with C1,1 functions can be converted into equivalent convex optimization problems by using the proposed convexification method. Finally, an example is shown to illustrate how a monotone non-convex optimization problem can be transformed into an equivalent convex minimization problem.
