It is shown that the resulting distribution of halo masses strongly depends upon the choice of free parameters in the three algorithms, and therefore much care in their choice is needed. For many para...

We study the ranking profiles that correspond to the social structures that are most effective in sustaining cooperation in equilibrium, that is, social structures that s...
