An algorithm for solving largescale nonlinear ' programs with linear constraints is presented. The method combines efficient sparsematrix techniques as in the revised simplex method with stable quasiNewton methods for handling the nonlinearities. A generalpurpose production code (MINOS) is described, along with computational experience on a wide variety of problems.

We present an extension of the Simplex method for solving problems with piecewiselinear functions of individual variables within the constrains of otherwise linear problems. This work generalizes a previous work of Fourer that accommodate piecewiselinear terms in objective functions. The notion of nonbasic variable is extended to a variable fixed at a breakpoint. This new algorithm was implemented through an original extension of the XMP library and successfully applied to solve an industrial problem.

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 feasiblepoint activeset methods for QP. This framework defines a class of methods in which a primaldual search pair is the solution of an equalityconstrained subproblem involving a “working set ” of linearly independent constraints. This framework is discussed in the context of two broad classes of activeset method for quadratic programming: bindingdirection methods and nonbindingdirection methods. We recast a bindingdirection method for general QP first proposed by Fletcher, and subsequently modified by Gould, as a nonbindingdirection method. This reformulation gives the primaldual search pair as the solution of a KKTsystem formed from the QP Hessian and the workingset constraint gradients. It is shown that, under certain circumstances, the solution of this KKTsystem may be updated using a simple recurrence relation, thereby giving a significant reduction in the number of KKT systems that need to be
