"The local contact search is a numerical procedure of a contact algorithm which is used for computing of a penetration vector between so-called master and slave segments of contact surfaces. There are several approaches. In this paper the minimum distance problem between the master segment and the integration point of the slave segment is used. For quadrilateral elements this approach leads to the system of two nonlinear equations. For its solution several methods was tested (Newton-Raphson method, least square projection, method of steepest descent, Broyden's method, BFGS method, DFP method and simplex method) and efficiency was compared." . .
