Parker Banks / mbeddedNets

Generates neural net instances through genetic algorithm for use in task learning by m3pi. Reward determined by detection of black areas on arena floor, or by amount of area explored in limited time. Due to memory size, limited # of nets.

Dependencies:   Ping m3pimaze mbed
