Panel to set the population structure
Populations have different characteristic structures determined by the type of interactions of one player with other members of the populations.
 Structure

 meanfield/wellmixed populations
 Well mixed population without any structures, i.e. groups or pairwise encounters are formed randomly. This is often called the meanfield approximation.
 complete graph
 x
 linear lattice
 The players are arranged on a straight line  that is actually on a ring in order to reduce finite size and boundary effects  and interact with equal numbers of neighbors to their left and right.
 square lattice
 All players are arranged on a rectangular lattice with periodic boundary conditions. The neighborhood size may be four (von Neumann) or eight (Moore neighborhood).
 honeycomb lattice
 The players are arranged on a hexagonal or honeycomb lattice interacting with their six nearest neighbors.
 triangular lattice
 The players are arranged on a triangular lattice interacting with their three nearest neighbors.

 random graph
 Randomly drawn bonds/connections between players. The neighborhood size determines the average number of bonds (average connectivity) of one player, i.e. the players interact with different numbers of other individuals.

 Random undirected links
 Fraction of bonds that get randomly rewired to obtain a small world network out of some underlying regular lattice. Note that fractions close to one will require an enormous number of rewired bonds.
