Searching a global optimum point in a multimodal performance surface is unavoidable in many DSP applications and, in these cases, the algorithms based on gradient estimation such as the method of steepest decent are unsuitable. To overcome this problem, a random search algorithm called 2-D genetic optimizer algorithm (2-D GOA) is developed in this paper. In addition, to illustrate the advantage of 2-D GOA, an application of this algorithm in sequence image coding is given also
