The probability of nonconvergence and its spatial effects in the hard red winter wheat market
Nonconvergence in commodity markets has caused some market participants to question the effectiveness of using futures contracts to effectively set prices. This failure of the price discovery function of the futures market increases a farmer’s basis risk exposure when hedging their grain. A …

The extreme point mathematical programming problem
… of such algorithms. Insightful examples of nonconvergence are also provided. Two finitely convergent algorithms are also presented. One of these is a cutting plane based procedure while the other is a branch and bound scheme. Computational experience with both algorithms is given.

Efficient direct-method parallel circuit simulation using multilevel node tearing
… avoids the problem of slow convergence or even nonconvergence, which could occur when relaxation-based techniques are applied. However, the parallelism of the direct method is not as obvious as that of the relaxation technique. The parallelism in the LU factorization without tearing has been …

Structural Optimization Using Geometric Programming and the Integrated Formulation
… linearization of a nonlinear problem, i.e., nonconvergence due to nonconvexity. The method presented here first isolates a convex subset of the possibly nonconvexfeasible region. The Generalized Geometric Programming method generates a series of such convex regions that converge to a solution …

Experimental Design Optimization and Thermophysical Parameter Estimation of Composite Materials Using Genetic Algorithms
… methods show instabilities resulting in nonconvergence when used with models that contain correlated or nearly correlated parameters. The objectives of this research were to develop systematic and reliable methodologies for both Experimental Design Optimization (EDO) used for the …
