A little over two years ago now I wrote a review for The Crew, Ubisoft's racing-game-slash-MMO hybrid, a game that touted all of America as its map. And it made good on that promise--I spent a long time just admiring the scenery contained therein. That's about all I admired though, because it was a pretty damn mediocre racing game. And here we are again, with The Crew 2. Another game with an identity crisis, of sorts. Another game where the map is the biggest draw--and it's a fantastic draw, let me say that up front.

Optimization for machine learning is essential to ensure that data mining models can learn from training data in order to generalize to future test data. Data mining models can have millions of parameters that depend on the training data and, in general, have no analytic definition. In such cases, effective models with good generalization capabilities can only be found by using optimization strategies. Optimization algorithms come in all shapes and sizes, just like anything in life. Attempting to create a single optimization algorithm for all problems would be as foolhardy as seeking to create a single motor vehicle for all drivers --there is a reason we have semi-trucks, automobiles, motorcycles, etc.
