 **PayOffCalculator**: The payoff calculator is the calculation class of the APGG framework.
  It is used to calculate the payoff each organism receives based on its decisions. For example, in a PGG with punishment, the punishment cost and the punishment fine as well as the rewards from cooperation or defection are calculated. Other game modes can be implemented by overloading this class.
 
-The payoff calculation for the PGG with punishment is a two step process. In the first step, the base costs, fines and payoff are calculated. The second step calculates the individual payoff based on the organism's decision. Depending on its decision, the organism has to pay a punishment cost or a punishment fine out of its individual payoff. There are payoff calculators for different scenarios: Asymmetric Payoff calculator - a calculator, which calculates the payoff based on a spatial tier list. Everyone transfers his individual payoff into a group pool. After that, everyone gets his individual payoff out of this pool based on his rank in the group [@smith2007rank].

-The GroupLevelPayoffCalculator [@hintze2020inclusive] is a calculator where everyone transfers a predefined part of his payoff into a group pool for group members to share rewards with each other. After everyone has paid into this pool, the pool will be split by the number of group members and the value will be added to the individual payoff.
