VALDERRAMA, José O  y  FAUNDEZ, Claudio. Numerical Parameters in the Genetic Algorithms Method for Calculating the Solubility and the Sublimation Pressure. Inf. tecnol. [online]. 2006, vol.17, n.6, pp.119-124. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000600018.

The effect of some numerical parameters on the determination of the sublimation pressure of a solid using solubility of the solid in a high pressure gas was specially analyzed. The study is based on a paper presented by Valderrama y Zavaleta (2005) in which genetic algorithms are used as optimization method. The values of some parameters involved in the genetic algorithm method such as number of individuals, number of generations, the crossover probability and the mutation probability, were not analyzed by these authors. In this study the results obtained by varying the values of these parameters using the deviation in the solubility as the objective function is analyzed with details. The study allows to conclude on the effect of these parameters and on the best values of the parameters for the cases studied.

Palabras clave : sublimation pressure; gas-solid solubility; equations of state; genetic algorithms.
