- randomized beam search method to seek maximally fit hypothesis
- GAs vs. Backprop - GD moves smoothly from one hypothesis to a new
one which is very similar
- GAs move much more abruptly - replacing a parent with an
offspring that maybe radically different
- GA is therefore less likely to fall into the same kind of local
minima that plague GD
- GAs have their own problems - Crowding
