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.

- 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.
