Along the bottom of the applet there are several buttons to control the execution and the speed of the simulations - for details see the [[EvoLudo:Graphical User Interface|''EvoLudo'' GUI documentation]]. Of particular importance are the [[EvoLudo:Parameters|parameters]] button and the [[EvoLudo:Dataviews|data views]] pop-up list along the top. The former opens a panel that allows to set and change various parameters concerning the game as well as the population structure, while the latter displays the simulation data in different ways.

Data views

Strategies - Structure

Snapshot of the spatial arrangement of strategies.

Strategies - Structure 3D

3D view of snapshot of the spatial arrangement of strategies.

Strategies - Mean

Time evolution of the strategy frequencies.

Simplex \(S_3\)

Strategy frequencies plotted in the simplex \(S_3\). If no calculation is running, mouse clicks set the initial frequencies of strategies and stops the calculations otherwise (for the ODE solver it switches to backwards integration).

Phase plane 2D

Frequencies plotted in the phase plane spanned by the population density (\(u + v = 1 - w\)) and the relative frequency of cooperators (\(f = u / (u + v)\)). Again, mouse clicks set the initial frequencies of strategies, stop the simulations or switch to backward integration

Fitness - Structure

Snapshot of the spatial distribution of payoffs.

Fitness - Structure 3D

3D view of snapshot of the spatial distribution of payoffs.

Fitness - Mean

Time evolution of average population payoff bounded by the minimum and maximum individual payoff.

Fitness - Histogram

Snapshot of payoff distribution in population.

Structure - Degree

Degree distribution in structured populations.

Game parameters

The list below describes only the parameters related to the public goods game and the population dynamics. Follow the link for a complete list and descriptions of all other parameters such as spatial arrangements or update rules on the player and population level.

--interest <r>
multiplication factor \(r\) of public good.
--cost <c>
cost of cooperation \(c\) (investment into common pool).
--lonecooperator <l>
payoff for a cooperator if no one else joins the public goods interaction.
--lonedefector <l>
payoff for a defector if no one else joins the public goods interaction.
--basefit <b>
baseline reproductive rate of all individuals. The effective birthrate is affected by the individual's performance in the public goods game and additionally depends on the availability of empty space.
--deathrate <d>
constant death rate of all individuals.
--init <d,c,e>
initial frequencies of defectors d, cooperators c and vacant space e. Frequencies that do not add up to 100% are scaled accordingly.
--inittype <type>
type of initial configuration:
frequency
random distribution with given frequency
uniform
uniform random distribution
monomorphic
monomorphic initialization
mutant
single mutant in homogeneous population of another type. Mutant and resident types are determined by the types with the lowest and highest frequency, respectively (see option --init).
stripes
stripes of traits
kaleidoscopes
(optional) configurations that produce evolutionary kaleidoscopes for deterministic updates (players and population). Not available for all types of games.
