6.4 Discussion

The truck backer-upper problem is considerably more difficult than the mountain
car problem, and this is primarily because of the fragility and sensitivity of this
problem. In other words, small and incorrect actions may easily result in the truck
jack-knifing, which is an undesirable configuration. Yet, we are still able to find a
