+1 I'd also add that genetic algorithms are for optimization, and can't really be compared with most of the algorithms in that chart. It'd be a sub-level where different optimization techniques for finding model weights, for each type of approach (classification, clustering etc)are compared.

Most (all?) of the algorithms on the chart iteratively optimize an objective. However, most of the objectives are convex or otherwise admit an optimization strategy that performs better than a genetic algorithm.

I believe you are repeating what I said (?). All of the algorithms have different methods of arriving to an objective function and leveraging it's results. Yet, most share the same problem in terms of optimizing it, and yes, most choose other routes.
