Abstract

An algorithm for gauge fixing to the minimal Landau gauge in lattice QCD is described. The method, a combination of an evolutionary algorithm with a steepest descent method, is able to solve the problem of the nonperturbative gauge fixing. The performance of the combined algorithm is investigated on $8^{4}$ , $β = 5.7$ , and $1 6^{4}$ , $β = 6.0$ , lattice SU(3) gauge configurations.
