(2012-05)
In recent years, technological advances have resulted in a huge increment in data production as in the evolution of methods that facilitated its collection. The data that arrive continuously and massively with infinite ...
Un algoritmo para la aplicación de ingeniería reversa en sistemas biológicos
(2009-05)
Dado un conjunto de datos sobre un cuerpo finito Fq, queremos encontrar una función que interpole tales datos. Esta función se puede obtener por ingeniería reversa y es de la forma f = (f1, f2, ..., fn) : Fn −→ Fn donde ...
Aplicación de algoritmos meméticos en la programación de horarios de clases
(2012-08)
The objective of this research is to solve a scheduling problem using memetic algorithms which solve problems with a large number of variables and constraints. This method can be applied to different scheduling problems ...
