Starting with a project schedule where some activities are noncritical, is it ever optimal to crash any of these noncritical activities to meet a given deadline? The idea is that as you keep crashing to meet a tighter and tighter deadline, a noncritical activity could conceivably become critical, and then you might want to crash it. Experiment with the LAN project model to see if you can ever make this occur. Feel free to change the maximum reductions for the activities and/or their crashing costs per day.
