Members and non-members are all welcome to contribute a problem, solution, use case, benchmark, or combinations of the above.

Your contribution will be carefully reviewed, and we will contact you whether it is accepted or not. If accepted, we will work with you to deliver your contribution(s) to the public and assure your ownership. Your identity and/or internal details (of a solution) may be withheld from the public upon your request.

​

Please describe your contribution in natual language. The contribution may include one or more links. A contributed solution may be an algorithm, a program, or simply text. If you contribute a solution, use case, or benchmark, please also describe the target problem in natual language.

​

Each contributed problem, if GPS cannot find a solution from the contributions in GPS' knowledge base, will be posted as an unsolved problem, together with other problems that may be generated by GPS. Unsolved problems may be viewed by GPS members only in the "Announcements" member area.
