Population Size

Changing the population size to investigate behavior across scales within a static arena size (i.e., variable density). This criteria is functionally identical to Population Variable Density in terms of changes to the template expdef file, but has a different semantic meaning which can make generated deliverables more immediately understandable, depending on the context of what is being investigated (e.g., population size vs. population density on the X axis).

Cmdline Syntax

population_size.{model}{N}[.C{cardinality}]

• model - The population size model to use.

  • Log - Population sizes for each experiment are distributed 1...N by powers of 2.

  • Linear - Population sizes for each experiment are distributed linearly between 1...N, split evenly into 10 different sizes.

• N - The maximum population size.

• cardinality - If the model is Linear, then this can be used to specify how many experiments to generate; i.e, it defines the size of the linear increment. Defaults to 10 if omitted.

Examples

• population_size.Log1024: Static population sizes 1...1024

• population_size.Linear1000: Static population sizes 100...1000 (10)

• population_size.Linear3.C3: Static population sizes 1...3 (3)

• population_size.Linear10.C2: Static population sizes 5...10 (2)
