What to do for this assignment

1. Based on the contents of reference [1, p.543] in the related reading list, consider the following:
   • If some places in a Petri net have infinite capacity and some have finite capacity, is it an infinite capacity net or a finite capacity net?
   • Can the intial marking of a place be greater than its capacity?
   • If we define a Petri net with a strict transition rule, the concept of finite capacity is included in the description. Do we need a separate definition for a finite capacity net?

2. Do Exercise 4.
