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

mean-field/well-mixed populations: Well mixed population without any structures, i.e. groups or pairwise encounters are formed randomly. This is often called the mean-field 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.
star: x
super-star: x
wheel: x
random regular graph: x
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 graph (directed): x
scale-free graph: x
scale-free graph (Klemm): x
scale-free graph (Barabasi & Albert): x
linear asymmetric: x

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.
