Abstract
In this paper an advanced genetic algorithm is used to find the maximum nonlinearity of n-argument Boolean homogenous functions. The best nonlinearity for Boolean functions number of arguments n was searched, where n= 8, 10, 12, 14 and for the degree k of homogeneity such that 1<k<n. The experimental results that were reached prove that our genetic algorithm is a powerful tool to search for high nonlinearity. Results are presented in diagrams and tables.
