  We apply a stochastic method of minimizing the ground state energy in
variational calculations of light nuclei using the Refined Resonating Group
Model (RRGM). The method utilizes a bit representation of the width parameters
to be varied. To find the best possible set of width parameters we use
strategies familiar from biological evolution. Very complicated problems can be
solved in this way because the method is intrinsically parallel. The algorithm
can be used on parallel computers with any number of processors without any
change.
