dwave-preprocessing

dwave-preprocessing provides preprocessing tools for binary quadratic models (BQM) and presolve algorithms for constrained quadratic models (CQM).

import dwave.preprocessing

This package contains several preprocessing composites that can aid in solving BQMs and a presolver that can reduce a problem's redundant variables and constraints to improve the accuracy of CQMs. For details on underlying algorithms and usage, see the package's Reference Documentation.
