- Is there a standard definition of what constitutes a reduction
- in a logic programming language?
- In particular:
-
- - are system goal reductions counted?
- - are attempted goals in failed clauses also counted as reducitons?
- - are guard goals in committed-choice languages counted?
- - are output unifications in the body of a clause in committed-choice
- languages counted?
-
- Also, is the a difference between a reduction and a logical inference?
-
- I'd like to know the definitions of these terms so that I can
- compare the speeds of various logic language implementations.
