"Webb: The agent will get a +1 reward for each combat unit produced. 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.

Similarly, reward shaping (Mataric, 1994 ; Randløv and Alstrøm, 1998 ) is a technique to give the agent additional rewards in order to guide it during training.
