framework for an AI that can play magic-monkey only chimps
Genetic algoirthm + neural network = magic
A neural network was trained on BTD6 round data contained in the data folder. It was only trained on magic monkeys, so it can only use magic monkeys.
Data was collected through a DLL and the help of BTD-Mod Helper. The round # and magic monkey layout are inputted into the model, and the model outputs the probability that the player loses health.
The model is then used as part of the fitness function in a genetic algorithm to create the AI.
The trials in the video were all consecutive. AI had no exposure to these two maps, only trained on data from Monkey Meadows. Videos are sped up with a mod.

Uses model and map points to simulate a game plan with genetic algorithm for 100 rounds on CHIMPS. The provided map points and possible placements are for Monkey Meadows and obtained through a custom BTD6 mod. In the showcase, a server was set up to deliver the game plan to the BTD6 mod through GET and POST requests.
