see Flattener. Instead of moving to the places with the least amount of danger, move to the places you have been less often. Ofcourse depending on your configuration and segmentation. In case of a wavesurfer, recording every fired bullet instead of only the times the enemy really hit you, would result in a 'flat' movement => flattener. The biggest problem with a flattener is the decision when to switch to the flattener and when not. (pro tip: search the wiki for info)
