Practice Exercise In the model presented above, we were not allowed to change projects between years, i.e., we select projects, and we stick with them for the entirety of the planning horizon (3 years). How can the model be modified if we were allowed to change projects between years? Are there any assumptions you would need to make and/or any extra parameters that you might need? Would the variables change?
