  • Thank you for hosting this contest. I will not meet the deadline but I plan to continue to work on it and want to describe what I think is a different approach.

    In thinking about the problem, I see a damped system that has energy periodically added. The thought is similarly expressed by Member #815726. In order for the bag to continue oscillating, the system needs to be perturbed within a fairly narrow frequency range that is independent from the boxer's skill.

    So, I think an algorithm can be made to detect and count when energy above a certain threshold and at ~about a certain frequency is input in the system. In order to do that, I use a Goertzel algorithm to efficiently detect signal power within a certain frequency range.
