Like for example gaining experience points and making it through a level the fastest way possible?
Yep! Just keep it in mind that the algorithm will maximize the reward function, so it is possible that it will figure out that just speedrunning without harvesting any experience is still the easiest way to do so. This thing is used to find the best strategies to maximize the reward in the first place, not to mimic certain behavior. If you wish to make it mimic certain human-player like behavior, i believe it’s also possible, but will require some tinkering.
