Abstract:

We compare two types of coevolutionary tournaments, true and diffuse, in contests using a general-purpose, physics-based simulator. Previous work in coevolving agents has used true coevolution and found that populations tend to enter mediocre states. One way of alleviating these problems is through diffuse coevolution. Our results show that agents evaluated with diffuse tournaments are less specialized than those evaluated with true tournaments.
