The simulation has a small UI bug where the whole screen is not displayed. This happened in exporting from unity to WebGL.
The red bird is an agent that maintains a memory of which blue birds it has eaten. The red bird selects which target it tries
to go for based on a exploration/exploitation epsilon constant. If the bird selects to exploration it's target becomes the closest
blue bird to it. If the bird select exploitation it targets the closest blue bird in of the type that has had the largest average score.
The red bird only eats untill it's full, it is full when it's food score is above 800.
The blue birds spawn in a of a random type [1-9] and a random score [1-100]*type. Therefore eventually the red bird will always go for
blue birds of type 9 eventually. The blue birds decrease in value and size over time.
The code for this simulation can be downloaded HERE there the visual bugs will not be present.
