It does have crossover, doesn't it? There's a GitHub link at the bottom which gives us this: https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/machine-learning/genetic-algorithm/manage-round.js https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/... And that seems to call into createCrossBreed() in here: https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/machine-learning/create-instance.js https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/... And that gets a parentChooser callback, which seems to be cw_chooserParent() from here: https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/generation-config/pickParent.js https://github.com/red42/HTML5_Genetic_Cars/blob/master/src/... And that has some swap points and a thing that toggles between parents when some index matches one of two values. I'm not really a JS programmer or a GA expert, but it looks like crossover to me.
