Tinkering with Genetic Algorithms: Forecasting and Data Mining in Finance and Economics
In two previous papers [13,14] genetic algorithms were presented that permit the search for dependencies among sets of data (univariate or multivariate time-series, or cross-sectional observations) . These algorithms — modeled after genetic theories and Darwinian concepts, such as natural selection and survival of the fittest — permit the discovery of equations, in symbolic form, that re-create or, at least, mimic the data-generating process. This paper discusses some of the computational issues and difficulties that may arise when the genetic algorithm is applied, and suggests ways to improve the algorithm’s performance.
