They apply an array of AI techniques to playing Pac-Man. Solutions By company size Pacman. In order to escape, he needs to figure out which corridors, if any, lead to an exit and freedom, rather than the certain doom of a pit or a ghost. A solution is defined to be a path that collects all of the food in the Pacman world. Pac-Man manages to find a short and stright-forward solution. 2 stars Watchers. Implemented Pacman agents that "bust ghosts"using Hidden Markov Models and Particle Filtering. Now consider a CSP forming a circular structure that has n variables (n > 2), as shown below. Now, rather than giving Pacman control over a ghost move once in the game, the special power allows Pacman to once make a ghost act randomly. using Linux/Ubuntu 18. For example, we can charge more for dangerous steps in ghost-ridden areas or less for steps in food-rich areas, and a rational Pacman agent should adjust its behavior in response.
