GMSE (version 1.0.0.2)

make_costs: COST initialisation

Description

Initialise the cost array of the G-MSE model.

Usage

make_costs(AGENTS, RESOURCES, res_opts, lnd_opts, min_cost)

Arguments

AGENTS

The array of agents produced in the main gmse() function

RESOURCES

The resources array produced by the resource function within GMSE

res_opts

A binary vector produced by the GMSE function defining what types of stakeholder interactions with resources (scaring, culling, castration, feeding, help_offspring) are permitted

lnd_opts

A binary vector produced by the GMSE function defining what types of stakeholder interactions with the landscape (tend_crops, kill_crops) are permitted

min_cost

The minimum cost that any agent (stakeholder or manager) incurrs for performing one action. This value is also set as an option in the main gmse() function (minimum_cost). This cost is recommended to be set to a value of 10, which gives managers increased precision when adjusting costs. For example, if the mimimum cost for a stakeholder performing an action is low, then a small change in the mimimum cost could halve or double the number of actions performed from the manager's perspective, with no options in between; hence the benefit of having a high mimimum cost combined with a higher agent budget (see the main gmse() function)

Value

A three dimensional array of initialised cost values for agent (manager and stakeholder) actions of the same dimensions as the ACTION array in GMSE

Examples

# NOT RUN {
COST <- make_costs( AGENTS = AGENTS, RESOURCES = starting_resources,
res_opts = user_res_opts, lnd_opts = user_lnd_opts, min_cost = minimum_cost);
# }
