In this note, we introduce and briefly study a non-binary analogue of the " classical " Walsh transform. It is shown that this transform allows to rewrite the definition of normalized epistasis in terms of generalized Walsh coefficients, in a way which is both practical and elegant. Some examples are included, aiming to give a first indication of the… (More)
In this note, we indicate how the basic machinery of Walsh transforms can be generalized from the binary case ([3, 4]) to multary alphabets. Our main results show how Walsh coefficients are related to partition coefficients and how they may be used to calculate schema averages.
BACKGROUND The appropriate care for people with cardiovascular risk factors can reduce morbidity and mortality. One strategy for improving the care for these patients involves the implementation of evidence-based guidelines. To date, little research concerning the impact of such implementation strategies in our setting has been published. Aims. To evaluate… (More)
Genetic Algorithms (GA) are a mathematical tool based on the mechanisms of the evolution of species and are successfully applied mainly as function optimizers. They look for the most fit solution for a particular problem, by means of the evolution of populations of data that, once codified –generally a binary encoding– use genetic operators which… (More)
