Algoritmos evolutivos en la solución de problemas de estimación de parámetros
(2009-02-20)The global problem to determine the values of some parameters in dynamicalmodels knowing experimental results is frequently known as Parameters EstimationProblem and it appears in many areas of sciences. So is clear that ... -
Anillos separables, de baer y pp-anillos
(2009-02-20)Keimel introduced the notion of proyectability in the class of lattice-ordered ringsand f-rings in [5]. Here we introduce a similar notion forgeting the lattice and orderedstructure of the ring and interpretating the ... -

Heuristic analysis of a near optimal approximation algorithm for the determination of investment options
(2009-02-20)When cash becomes available in a company, there are several strategies that allowus to benefit from it. The problem is how much to invest, for how long, and using whichof the investment options in order to get the maximum ... -
New results with scatter search applied to multiobjective combinatorial and nonlinear optimization problems
(2009-02-20)This paper introduces two variants of a multiple criteria scatter search to deal withnonlinear continuous and combinatorial problems, applying a tabu search approach asa diversification generator method. Frequency memory ... -
Una caracterización sobre las soluciones para el problema de reaprovisionamiento conjunto
(2009-02-20)In this paper an introduction is given to a multiple-item inventory problem, knownas the Joint Replenishment Problem (JRP). This is a real world problem which hasbeen extensively studied. The JRP has a continuous decision ...
