Modeling at different levels Agent-based models can be written at different levels. For example, one model may have agents that are populations of wolves and sheep, whereas another model may have agents that are individual wolves and sheep. Write a description of how packs of wolves interact with flocks of sheep at the group level. Now write a description of how individual sheep interact with individual wolves. How are your descriptions different? What phenomena are you describing? At what times would the group level description be helpful? At what times would the individual level description be helpful?
