Siphons have been used for thousands of years to transfer fluids without the use of pumps or power and are present in our daily lives. Paradoxically, it is only in recent decades that the operation of siphons has been fully clarified, which is now un

Siphon computation is a basic step for developing siphon-based deadlock control approaches in a Petri net (PN) system. This work studies the enumeration of minimal siphons in a PN. Due to the fact that the number of siphons in a PN theoretically grow
