Predicate symbols in upper case?[edit]

Isn't there a problem with notation here?

A(X,Y) :- X+Y>0, B(X), C(Y).

In logic programming, variables are in upper case while predicate symbols are in lower case:

a(X,Y) :- X+Y>0, b(X), c(Y).

So shouldn't predicate symbols be changed to lower case? Pgr94 (talk) 14:03, 13 March 2008 (UTC)

relation to SMT?[edit]

What is the relationship between constraint logic programming, and satisfiability modulo theories? I believe I asked a similar question about the relationship to answer set programming; one answer seems to be that some systems actually provide the interpretation (logic) or theorems that actually give the solution, while others only reply yes/no as to whether the constraints can be satisfied. However, a more detailed compare-n-contrast of the methods & results would be appreciated. linas (talk) 19:15, 16 June 2011 (UTC)

Prolog III, Prolog IV, Prologia and history of CLP[edit]

The versions of Prolog can be downlaod "as-is" at

The versions include Prolog III and Prolog IV from Prologia.

Mention of Prolog III is not minimal in WP and I could see no mention of Prolog IV outside the Byte article reference.
