Framework 

Evolutionary Mechanism with Reputation 

This work is supported by the Cyprus Research Promotion Foundation grant TΠE/ΠΛHPO/0609(BE)/05

Background

Evolutionary Mechanism, choose n workers out of a pool of N

Evolutionary Mechanism (No Reputation)  

Conditions for Eventual Correctness (No Reputation)  Simulations
