I'm looking for some interesting research in the topic of constraint logic
programming or constraint satisfaction programming. I'm already familiar with
Jaffar's and Lassez' work and also with the Prolog III approach.
1.) Any information about related research, esp. implementation of this
paradigm for different other domains than R (as in CLP(R)) are of
interest.
2.) I am also interested in applications and experience in any constraint
satisfaction based language that may contribute to an evaluation of
the constraint satisfaction paradigm.
I appreciate any response, Thanks

(pronounced Wim) discussed a constraint language called Bertrand. This language was developed by Wm. in connection with research leading to his Ph.D. His Ph.D. thesis has since been published as a distinguished thesis by one of the computer science publishers. It's called Constraint Languages. It's fairly recent. Don't know the publisher right off hand. Phil Miller

See my article, entitled 'Dependency Propagation', included in IJCAI87 Proceedings, though, I'm afraid, this is not very well-written; less than half of it talks about constraint programming, and natural language is what the rest of it is about. I should work out its constraint programming part in a more complete form. A crucial difference between my DP and others (CLP, Prolog III, etc.) is that DP deals with constraints on combinatorial objects (i.e., the term structures of logic) whereas the constraints considered in the other approaches are about arithmetic objects (rational numbers or real numbers). Another difference is that in DP we look upon processing as constraint transformation. Since the constraint is the program here, processing is a sort of program transformation. Currently under way is an implementation of the interpreter according to DP. This implementation is being done in language C. The first phase of the work is supposed to be finished within one month or two, and will be applied to a natural-language parser based on a unification grammar formalism. I hope this is of some interest to you. HASIDA, Koiti ('HASIDA' is my family name) Machine Inference Section
