- | |||
- | Agents are defined as entities embedded in an environment with which they interact; they are able to see it through sensors and act upon it through actuators (Russell and Norvig 1995). | ||
- | |||
- | In the model the agents occupy cells that depict the agent identification.\\ | ||

- | |||
- | Agents have the following attributes: | ||
- | |||
- | * //Vision//: value (number of cells in the neighborhood) defining the range of vision of the agent to search for resources on the landscape. | ||
- | |||
- | * //Resources spent to survive//: value defining the amount of resource necessary to survive at each model step. | ||
- | |||
- | * //Maximum absorption of resources//: value defining maximum capacity for absorption of resources of agent per model step. | ||
- | |||
- | * //Resources spent to move//: value representing the amount of resources an agent spends to move across a cell per model step. | ||
- | |||
- | * //Average age//: value that represents the average of a normal distribution that determines the likelyhood of agent death at a model time step. | ||
- | |||
- | * //Type//: represents the group which the agent belongs. | ||
- | |||
