Look at the —the hollow circles acting as reservoirs of state. They hold the "tokens," those indistinguishable quantum dots of existence. A place is not merely a location; it is a condition. It is the "true" in a logic gate, the "full" in a buffer, the "waiting" in a queue. When you look at a place, you are looking at the static memory of the world.
These are computed via standard Markov chain solvers (Gauss-Seidel, iterative methods) or simulation for large models. Look at the —the hollow circles acting as
This is the ghost in the machine. When immediate transitions fire, the system passes through states that technically do not exist in time. These are "vanishing markings"—states that are entered and left in zero time. To an external observer, they never happened. But to the mathematician analyzing the net, they are the hidden gears. The GSPN must mathematically eliminate these ghost states to derive the , stripping away the transient logic to reveal the steady, beating heart of the stochastic process. It is the "true" in a logic gate,
