For the game you are given source code and provided with 2 other player algorithms, one is an algorithm to find the closest points/prizes and the second is to find the largest points/prizes. They said they like to do this because the algorithm you pick is open ended, which is not actually true because the easiest algorithm to use would be a weighted average approach to finding the points/prizes. There were also one followup question about changing the "rules" of the game and how it would affect the algorithms.
Sigiloso
For whatever reason I was not able to think of using the weighted average approach at the time (it seems so simple and obvious now) and went a different, less effective approach.
