Flappybird

Implement Genetic Algorithm to play Flappy Bird

How the bird makes decision?

The AI uses Neural Network with 5 attributes to make decision whether the bird should flap or not:

Inputs

• Height of the bird
• Height of the top pole
• Height of the bottom pole
• Distance between bird and closest bird
• Velocity(how much flap power) of the bird

Outputs

• Probability (0 - 1) (flap if prob > 0.5)

How the bird improves on their decision-making?

I make use of Genetic Algorithm: -> Create population of birds (the more the faster the AI converges) -> Let it play with their own brain (making own's decision) -> The best one (highest fitness score) get mutated and get copy to the next generation
