Geometric views of the generalized Fischer-Burmeister function and its induced merit function

Abstract. In this paper, we study geometric properties of surfaces of the generalized Fischer-Burmeister function and its induced merit function. Then, a visualization is proposed to explain how the convergent behaviors are influenced by two descent directions in merit function approach. Based on the geometric properties and visualization, we have more intuitive ideas about how the convergent behavior is affected by changing parameter. Furthermore, geometric view indicates how to improve the algorithm to achieve our goal by setting proper value of the parameter in merit function approach.
