A few facts on productions systems. 1. Haunt consists of 1500 productions and requires 160K words of memory on a KL10. (So Frumps is a bit bigger than Haunt.) 2. Expert systems (R1, XSEL and PTRANS) written in a similar language consist of around 1500-2500 productions. 3. An expert system to perform VLSI design (DAA) consists of around 200 productions.
