| Artificial Intelligence (AI) is an important part of many computer games, where it's often used to create dynamic challenges for players to overcome. In this problem solving task, your objective is to create an AI controller for a space ship in a simple 2D game. Survive for as long as you can by dodging incoming hazards, and earn a high score in Challenge Mode by shooting asteroids along the way.

| - | The game can be run in two modes. In **Training Mode**, the stream of asteroids that your ship files through will always be the same after each reset. This can be useful while you test your code, but any high scores that you tally won't get counted. In **Challenge Mode**, the stream of asteroids will be different each time, but your high scores will be saved when your ship meets its end. | + | The game can be run in two modes.
