Comparing an experimental and a theoretical line shape can be achieved by a Genetic Algorithm (GA) based on an analogy to the mechanics of natural selection. Such an algorithm is able to deal with complex non linear models, and can avoid local minima. We have used this optimization tool in the context of edge plasma spectroscopy, for a determination of the temperatures and fractions of the various populations of neutral deuterium emitting the D α line in two configurations of Tore Supra: ergodic divertor and toroidal pumped limiter .
