I'm having a hard time getting the program in Figure 13.13 to run correctly. I have included the clauses on page 305. When I run

andor(a, Solution).

I get an error saying:
ERROR: evaluate/2: Undefined procedure: h/2

Is there an error in the code? In procedure evaluate there is a call to h(Node, H). Shouldn't this rather be f(Node, H)? I try this but when I run the above command I get "no" as a result.

Please help!!!

I downloaded this program (I think you mean 13.12 as there is no 13.13) from there website : http://www.pearsoned.co.uk/highereducation/resources/bratkoprologprogrammingforartificialintelligence3e/

and tried to run it and found the sime problem, I don't think it is meant to be f(Node,H) as this call fails always.

I for one am horribly dissapointed by both this textbook and the lack of tutorial matter for this subject...
