We present a numerical algorithm for finding real non-negative solutions to a certain class of polynomial equations. Our methods are based on the expectation maximization and iterative proportional fitting algorithms, which are used in statistics to and maximum likelihood parameters for certain classes of statistical models. Since our algorithm works by iteratively improving an approximate solution, we and approximate solutions in the cases when there are no exact solutions, such as overconstrained systems.
