JESS: Does the idea of node sharing original to Jess?

[Bat-Odon]

Let me reconfirm a statement in the Jess manual.

 

You wrote "There are two simple optimizations that can make Rete even better
." in the Rete Algorithm chapter.

 

Do you mean the idea of sharing pattern and join nodes original to Jess?

 

Thank you,
