Use arrow keys (←,↑,↓,→) to move the robot(s) (blue) to the goal (outlined).
Adjust the number of robots below:
This tasks examines how task completion time scales with the number of robots.
Having trouble? See hint.
If a task requires twice as much time as for one robot with two robots, 3x times as much with three robots, and 4x with four robots, we say the task scales linearly. If a task requires 4x times the time with two robots, 9x with three robots, and 16x with four, we say the task scales quadratically.
Knowing how a task scales with robot number lets us describe task difficulty.
