    spaces‚ each of which is defined by a linear inequality. 2) What is an infeasible solution? How is this condition recognized in simplex method? A infeasible solution is one that does not satisfies all linear and non-linear constraints. When the solution is along with the artificial variable even when the aolution is optimized then its is a infeasible solution 3) What is an unbounded solution? How is this condition recognized in simplex method? A linear program is unbounded if the optimal

    Methods for Convex and General Quadratic Programming∗ Philip E. Gill† Elizabeth Wong† UCSD Department of Mathematics Technical Report NA-10-01 September 2010 Abstract Computational methods are considered for finding a point that satisfies the secondorder necessary conditions for a general (possibly nonconvex) quadratic program (QP). The first part of the paper defines a framework for the formulation and analysis of feasible-point active-set methods for QP. This framework defines a class of methods

    blend. It did so based on the properties of available stocks and blend proportions suggested by the blender. Then‚ by the 60’s computers advanced quit a bit. Linear programming models were being solved by linear programming introduced by the refiner engineers. A process optimization program for nonlinear optimization that solved nonlinear programming problems was developed by IBM‚ called POP II. Then‚ immediately after‚ the GOP blending optimization system was developed that used the POP II system.
