Un algoritmo de programación geométrica basado en funciones penalidad-multiplicadoras.

Eduardo Ramos Méndez (1986)

Trabajos de Investigación Operativa

El trabajo presenta un nuevo algoritmo para la resolución de un problema de porgramación geométrica primal transformado. El método se basa en las técnicas de tipo lagrangiano aumentado y utiliza como penalidad funciones derivadas de la exponencial para las restricciones con un único término, y de la pérdida cuadrática para las restricciones con más de un término. El problema resultante se resuelve por medio de un método lagrangiano con iteración de tipo Newton, y los parámetros de penalización se...

Uniform Convergence of the Newton Method for Aubin Continuous Maps

Dontchev, Asen (1996)

Serdica Mathematical Journal

* This work was supported by National Science Foundation grant DMS 9404431.In this paper we prove that the Newton method applied to the generalized equation y ∈ f(x) + F(x) with a C^1 function f and a set-valued map F acting in Banach spaces, is locally convergent uniformly in the parameter y if and only if the map (f +F)^(−1) is Aubin continuous at the reference point. We also show that the Aubin continuity actually implies uniform Q-quadratic convergence provided that the derivative of f is Lipschitz...

Unilateral elastic subsoil of Winkler's type: Semi-coercive beam problem

Stanislav Sysala (2008)

Applications of Mathematics

The mathematical model of a beam on a unilateral elastic subsoil of Winkler's type and with free ends is considered. Such a problem is non-linear and semi-coercive. The additional assumptions on the beam load ensuring the problem solvability are formulated and the existence, the uniqueness of the solution and the continuous dependence on the data are proved. The cases for which the solutions need not be stable with respect to the small changes of the load are described. The problem is approximated...
