When I run the cord below at Jupyter-notebook,

solver = SCIP_CMD(path=scip_file, threads =7)

it returns the following error.

SCIP_CMD.__init__() got an unexpected keyword argument 'threads'

I checked the git-hub code but I could not find the keyword "threads" . Is the SCIP solver multi-threaded in PULP now? I downloaded SCIP ver 8.0.3 and pulp ver 2.7.0.

SCIP is by default single-threaded, which you could have figured out by searching previous asked questions

  • Thanks! Looking at the following website, it seems that multithreading is possible. But is it difficult? https://coin-or.github.io/pulp/technical/solvers.html#pulp.apis.SCIP_CMD – Takeshi Matsuda Mar 08 '23 at 02:19
  • You can set that all you want in from the pulp-end. SCIP is single-thread only (unless you use UG as an external parallelization framework, but I don't think you will be able to do that from pulp) – Leon Mar 09 '23 at 15:28
