Actually, there has been a company trying to sell constraint programming as a spreadsheet. I don't think it still exists. But I have no details.
But just by googling "constraint programming spreadsheet" you will find a paper reporting on how cp is integrated into OpenOffice. Didn't check myself though. To me it is not so clear whether a spreadsheet is really the right thing to have as I am not so sure how many people out there are really spreadsheet power users who could benefit. Maybe most people only edit a cell here and there? But maybe I am wrong.

I wish I had time to work on this. If I did I'd want to look into building an interface between Gecode and the OpenOffice spreadsheet. It seems to me that one thing that's kept constraint programming from the masses is that one has to be a programmer to use it. If it were somehow available though a familiar interface like a spreadsheet (even in a limited form), I think it would become much more widely known and used. (It might also help OpenOffice take marketshare from Excel.) What do you think? How hard would it be to do something like this in a way that would provide a useful feature for spreadsheet users? -- -- Russ Abbott _____________________________________________ Professor, Computer Science California State University, Los Angeles o Check out my blog at http://russabbott.blogspot.com/ On 1/18/06, Christian Schulte <[EMAIL PROTECTED]> wrote: [I think that this might be of some interest as Gecode inherits some ideas (computation spaces) from Oz. Christian.] We would like to announce the release of Gecode 1.0.0 http://www.gecode.org/ Gecode is an open, free, portable, accessible, and efficient environment for developing constraint-based systems and applications: open Gecode is radically open for programming: it can be easily interfaced to other systems. It supports the programming of new propagators (as implementations of constraints), branching strategies, and search engines. New variable domains can be programmed with the same efficiency as the finite domain and integer set variables that come predefined with Gecode. free Gecode is distributed under a BSD-style license. All of its parts including documentation, implementations of global constraints, and examples are available as source code. portable Gecode is implemented in C++ that carefully follows the C++ standard. It can be compiled with modern C++ compilers and runs on a wide range of machines (including 64bit machines). accessible Gecode comes with extensive reference documentation that allows to focus on different programming tasks like modelling, implementing propagators, and implementing variable domains. efficient Gecode offers competitive performance with respect to both runtime and memory usage. allows contributions Gecode is designed to facilitate contributions on top of it. CP(Graph) and CP(Map) providing graph and map variables for constraint programming is available as a first contribution built on top of Gecode. Gecode and contributions built on top of it are available from http://www.gecode.org/ -- Christian Schulte, http://www.imit.kth.se/~schulte/ ____________________________________________________________________________ _____ mozart-users mailing list [email protected] http://www.mozart-oz.org/mailman/listinfo/mozart-users _________________________________________________________________________________ mozart-users mailing list [email protected] http://www.mozart-oz.org/mailman/listinfo/mozart-users
