Gecode: Community

Questions and Answers

You can contact the Gecode developers and users via a mailing list. But, please make sure to not waste your time and the time of others:

  • Please check Gecode's documentation first.
  • Please check the archive of the Gecode users mailing list as to whether a similar question has been asked before.
  • Please focus on questions specific to Gecode. For general questions about constraint programming more suitable forums exist.
  • Please provide sufficient detail: describe your platform (operating system, compiler, Gecode version) and your problem (what does not work, what do you want to do, what is the problem you observe) as accurately as you can.
  • Please do not contact individual developers: it is much better to build a comprehensive archive of questions and answers related to Gecode that can be useful for everyone. If you have any questions not suitable for the public mailing list, please do not hesitate to contact one of the authors directly.
  • Never ask for solutions to homework. The only more offensive thing you could do is to provide a solution on the mailing list if someone has violated the no homework policy!
