These models are similar to the Evolution and competition for resources models, but they add cultural evolutionary dynamics through behavior imitation. Several imitation biases are simulated: imitating the majority, the minority, the most successful, the most experienced, or the parents. Depending on the imitation bias, transmission fidelity, rate of behavioral innovation, and the mobility of agents, one can observe the emergence and spread of norms and traditions of sustainable or unsustainable resource use.
