Abstract: In this work we give a detailed look to the DFP method for solving unconstrained optimization problems. Section( 0 ), shows the history and developments of the method . Section (1), general theory of the problem is described , constricting on the practical side in the description . Section (2), Newton’s method is described . It constitute a solid base, both theoretical and practical , for the class of methods known as Quasi –Newton method. From this class comes the DFP method is described in section (3) . Detailed result on the DFP are shown in this work .Section (4) shows a practical implementation of the DFP method on quadratic function to test the theoretical results shown in the work.
Keywords: solving unconstrained optimization, described, constricting, theoretical and practical.
