Quadratic programming is one of the type of nonlinear optimization problems in which thernobjective function is quadratic and all the constraints are linear. There is no single methodrnavailable for solving a quadratic programming problem. So a number of methods have beenrndeveloped for solving quadratic programming problems. In this project concerns for convex andrnnon convex quadratic programming problems with Lagrangian,Wolfe’s and Beale methods.
