Deterministic CESS in the limit of vanishing errors.

The CESS can be categorized into two classes, the leading-eight norms (top) and the secondary-sixteen norms (bottom), respectively. In this table, the left most column indicates the original reputations of the donor and the recipient. The second column then shows the norm’s action rule and the third and fourth column its assessment rule. The rightmost column gives the condition for the norm to be a CESS. The symbol * indicates that the respective value can be either 0 or 1. In this table, the assessment rule for context (B,B) is not shown as it can be arbitrary. Given the respective entries R(B,B,*) and the environmental conditions , the optimal action S(B,B) is uniquely determined.
