Jacobian Smoothing Methods for General Nonlinear Complementarity Problems
(1997-10-13)We present a new algorithm for the solution of general (not necessarily monotone) complementarity problems. The algorithm is based on a reformulation of the complementarity problem as a nonsmooth system of equations by ... -
k-Plane Clustering
(1998)A finite new algorithm is proposed for clustering m given points in n-dimensional real space into k clusters by generating k planes that constitute a local solution to the nonconvex problem of minimizing the sum of squares ... -
Limit analysis of frictional block assemblies as a mathematical program with complementarity constraints
(1999-02-15)The computation of the collapse loads of discrete rigid block systems, characterized by frictional (nonassociative) and tensionless contact interfaces, is formulated and solved as a special constrained optimization problem ... -
Lineality Removal for Copositive-Plus Normal Maps
(1994)We are concerned with solving affine variational inequalities defined by a linear map A and a polyhedral set C. Most of the existing pivotal methods for such inequalities or mixed linear complementarity problems depend on ... -
The Linear Convergence of a Successive Linear Programming Algorithm
(1996-12-03)We present a successive linear programming algorithm for solving constrained nonlinear optimization problems. The algorithm employs an Armijo procedure for updating a trust region radius. We prove the linear convergence ... -

Machine Learning via Polyhedral Concave Minimization
(1995-11)Two fundamental problems of machine learning, misclassification minimization [10,24,18] and feature selection, [25, 29, 14] are formulated as the minimization of a concave function on the polyhedral set. Other formulations ... -
Massive Data Discrimination via Linear Suppot Vector Machines
(1999-03-31)A linear support vector machine formulation is used to generate a fast, finitely-terminating linear-programming algorithm for discriminating between two massive sets in n-dimensional space, where the number of points can ... -
A Mathematical Model and Solution Methodologies for Optimal Process Planning on Four- Axis CNC Turning Centers
(1999)A new generation of Computer Numerical Control (CNC) machines, called four-axis turning centers has emerged and has been growing in use due to its versatility. Multiple turrets and spindles, automated material handling, ... -
