This is a more challenging task because the agent needs to learn 1) harvest resources when 2) produce barracks, 3) produce combat units once enough resources are gathered, 4) move produced combat units out of the way so as to not block the production of new combat units.

WebbThis is called reward shaping, and can help in practical ways in difficult problems, but you have to take extra care not to break things. There are also more sophisticated approaches that use multiple value schemes or no externally applied ones, such as hierarchical reinforcement learning or intrinsic rewards. WebbAndrew Y. Ng (yes, that famous guy!) et al. proved, in the seminal paper Policy invariance under reward transformations: Theory and application to reward shaping (ICML, 1999), which was then part of his PhD thesis, that potential-based reward shaping (PBRS) is the way to shape the natural/correct sparse reward function (RF) without changing the …
