	att_abstract={{Several numerical methods for solving nonlinear systems of equations assume
that derivative information is available. Furthermore, these approaches usually do
not consider the problem of finding all solutions to a nonlinear system, just one solution.
In this paper, we address the problem of finding all roots of a system of equations. Our
method makes use of a biased random-key genetic algorithm (BRKGA). Given a nonlinear
system, we construct a corresponding optimization problem, which we solve multiple
times, making use of a BRKGA, with areas of repulsion around roots that have already
been found. The heuristic makes no use of derivative information. We illustrate the approach
on seven nonlinear equations systems with multiple roots from the literature.}},
