This paper describes an application of a genetic programming to local contact search. Contact search process consists of two phases: a global search phase for finding the nearest node-segment pair and a local search phase for finding an exact local coordinate of the contact point within the segment. In this paper, the genetic programming is utilized for finding the function which approximates local coordinate of the contact point in the local search phase. The fundamental formulation of this method is described in detail, and its basic performance is demonstrated through some analyses.
