Abstract
This manual describes CILOG, a simple representation and
reasoning system based on the book Computational Intelligence: A
Logical Approach [1]. CILOG provides:
- a definite clause representation and reasoning system
- a simple tell-ask user interface, where the user can tell the
system facts and ask questions of the system
- explanation facilities to explain how a goal was proved, why an
answer couldn't be found, why a question was asked, why an
error-producing goal was called, and why the depth-bound was reached
- knowledge-level debugging tools, that let the user debug
incorrect answers, missing answers, why the system asks a question,
system errors, and possible infinite loops
- depth-bounded search, that can be used to investigate potential
infinite loops and used to build an iterative-deepening search
procedure
- sound negation-as-failure, that interacts appropriately with the
depth-bound
- ask-the-user facilities
- assumables
CILOG is a purely declarative representation and reasoning system.
It is intended as a pedagogical tool to present a simple logic that
can be used for AI problems. It is meant for programming in the small,
where you can axiomatize a domain, ask questions and debug the
knowledge base, without knowing how answers are produced.
There may be sophisticated problem-solving techniques used in finding
answers

We have many of the examples from the
book available.
This manual is also available in PDF format.
This is suitable for printing, but also contains hyperlinks.
