Add Ms. Pac-Man to the growing list of games being mastered by artificial intelligence (AI).
An AI system from Microsoft set the all-time high score for Ms. Pac-Man with 999,990 points – the highest possible score in the game. The previous high score was 933,580 points set by Abdner Ashman, a human from New York.
Microsoft explains how a technique called Hybrid Reward Architecture used 150 agents for a specific task in the game, like finding pellets, or avoiding ghosts. This allowed Microsoft’s AI to play a perfect game.
Then, the researchers created a top agent – sort of like a senior manager at a company – who took suggestions from all the agents and used them to decide where to move Ms. Pac-Man.“
The top agent took into account how many agents advocated for going in a certain direction, but it also looked at intensity.
