Escape from Zurg: An Exercise in Logic Programming. Escape from Zurg: An Exercise in Logic Programming. By Martin Erwig. Journal of Functional Programming, Vol. 14, No. 3, 253-261, 2004. In this article we will illustrate with an example that modern functional programming languages like Haskell can be used effectively for programming search problems, in contrast to the widespread belief that Prolog is much better suited for tasks like these.

Slow Frog: February 2012
https://slowfrog.blogspot.com/2012_02_01_archive.html
I'm slow, I'm French, I solve and program games in my free time. Wednesday, February 22, 2012. Hexiom, constraints and libraries. After my own forays into constraints programming, I received a comment by Pierre Schaus who solved the problem. This prodded me into looking at what were the available options in my preferred languages. I have learned a lot (but still have a long way to go) and I found two open-source libraries that are very powerful and quite performant, one for Java and the other for C .

A Policy-based Unified Multi-radio Architecture for Agile Mesh Networking. PUMA is a declarative constraint solving platform for policy-based routing and channel selection in multi-radio wireless mesh networks. We have developed a prototype of the PUMA system using the RapidNet. Declarative networking system deployed on the ORBIT. Testbed. PUMA consists of the following two building blocks:. Using the declarative networking. Extensible dynamic channel selection. Is to assign available channels to wireles...

Gecode/R: Constraint Programming in Ruby
http://gecoder.rubyforge.org/index.html
Gecode/R - constraint programming in Ruby. Constraint Programming in Ruby. Gecode/R is a Ruby interface to Gecode. An open source library for constraint programming. The interface is intended for people with no previous experience of constraint programming, aiming to be easy to pick up and use in practice. Describe your problem to the solver and then let it find solutions for you. Solve the equation system. Set up the variables, three integers with domain 0.9. Variables is an int var array( 3.

Help making ECLiPSe better! ECLiPSe is currently maintained by Joachim Schimpf and Kish Shen, with a small support grant from Cisco Systems. Both maintainers have been involved with the system for a long time, keep everything running, and continue development. Nevertheless, many ideas for improvements and additional functionality remain forever in the pipeline. As ECLiPSe is an open source. There are many areas where you can contribute even without having in-depth kowledge of the whole system:. ECLiPSe h...

Sur un air de balisette. Pdbset trace no longer working: problem solved. 8212; Alexandre Fayolle @ 14:01. I had a bad case of bug hunting today which took me 5 hours to track down (with the help of Adrien. I was trying to start a CubicWeb. Instance on my computer, and was encountering some strange pyro. Error at startup. So I edited some source file to add a pdb.set trace(). No pdb.py or pdb.pyc was lying around in my Python sys.path. The pdb.set trace function had not been silently redefined.
