Online BiqCrunch

You are free to try our solver by submitting your instances. Once the job has finished or the time-limit has been exceeded, you will receive an e-mail with the output.

The computer used to run the online solver is an Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz with 192 GB of RAM using Linux.

Note: When submitting a problem, the user agrees that the data will be stored and may be added to the BiqCrunch library of user instances with a credit to the user.

Online solver limits

There are some limitations when using the online version of BiqCrunch. You can solve problems having:

  • not more than 100 variables
  • not more than 5000 constraints

The time limit of the solver is set to 60 minutes. Note: the generic version uses a simple randomized rounding algorithm to try to generate feasible (integer) solutions from the results of the semidefinite relaxation at each node of the search tree. Specific heuristics are used for the Max-Cut and k-cluster problems.
