I hope you guys find this an interesting question. Imagine you want to implement a system that rewards people for their contributions (regardless of quality or any external assessment). What is a good model, considering the following conditions:
- It shouldn't reward people that contributes "excessively" only to gain whatever you're giving as reward. For example, if you're giving an award for 5 contributions, then you can't give that award again because of the sixth contribution.
- It shouldn't be too complex to be computationally unfeasible (although, if you know of something complex but interesting, I'd like to know about it).
As a clarification, the situation is such that you want to give a single award (instead of a variety of them).
Maybe you know some established theory dealing with this kind of stuff. Let me know if that's the case.
By the way, I searched in Google Scholar but I didn't find anything relevant.
