This code: (1) Generates data for the weak-selection mathematical model. This is contained in the "Generate_data_for_island_model_weak_selection" script. (2) Generates data for the agent-based simulation model, which accounts for stronger selection and finite populations. This is contained in the "Generate_data_for_agent_based_simulation" script. (3) Generates data for the version of the agent-based simulation model where there is no tag mutation, in which balancing selection is examined via tag fixation times. This is contained in the "Generate_data_for_balancing_selection_finite_pop" script.
