After an overview of the evolutionary algorithms field and their main ideas, we present some strategies that often intend to get off the problem of the initial parameters tuning. We focuse our attention about the comparizon of quite simple strategies, specially about the choice of genetic operators, the way to apply them and finally how each generation is built from the previous one. Knowing that it is not possible to reach an universal heuristic able to choose the genetic operators and to manage them, we present a method where the genetic operators themselves are evaluated according to their performance. The amelioration observed on some classical functions, with this method shows a future way to combine it thanks to a very simple steady state algorithm which has also given a good behaviour.
