  Based on the hurricane striking Puerto Rico in 2017, we developed a
transportable disaster response system "DroneGo" featuring a drone fleet
capable of delivering the medical package and videoing roads. Covering with a
genetic algorithm and a biased random walk model mimicking a drunk man to
explore feasible routes on a field with altitude and road information. A
proposal mechanism guaranteeing stochasticity and an objective function biasing
randomness are combined. The results showed high performance though
time-consuming.
