New Features

  • Add ConstrainedQuadraticModel.is_equal() and ConstrainedQuadraticModel.is_almost_equal() methods. See #1012
  • Add QuadraticModel.is_almost_equal() method
  • Support equality checks between quadratic models and binary quadratic models in BinaryQuadraticModel.is_equal(), BinaryQuadraticModel.is_almost_equal(), QuadraticModel.is_equal(), and QuadraticModel.is_almost_equal() methods.
  • Add GraphLike type hint to dimod.typing.
  • Add ConstrainedQuadraticModel.iter_constraint_data(), ConstrainedQuadraticModel.iter_violations() and ConstrainedQuadraticModel.violations() methods. See 971.
  • Added from_lp_file classmethod to ConstrainedQuadraticModel that reads input LP file and converts it to CQM instance.
  • ConstrainedQuadraticModel.set_objective now accepts an iterable.
  • Add ConstrainedQuadraticModel.check_feasible method.
  • Add random_bin_packing function with the same functionality as the (now deprecated) bin_packing.
  • Allow BinaryQuadraticModel and QuadraticModel to be divided by a scalar or squared. See #864, #984.
  • Add SampleSet.filter() method that returns a sample set with data rows filtered by a given predicate.
  • Add .to_dict() and .from_dict() methods to the sample inverter returned by the cqm_to_bqm function. The methods return a json serializable representation of the inversion for storage if needed. See 977.
  • Add random_multi_knapsack function with the same functionality as the (now deprecated) multi_knapsack.
  • Add random_knapsack function with the same functionality as the (now deprecated) knapsack.
  • Allow the offset of a BinaryQuadraticModel to be specified as a keyword argument.
  • Add PEP 561 compatibility to allow tools like mypy to auto-detect typing hints. See #980.

Upgrade Notes

  • The cls keyword argument of the chimera_anticluster function now does nothing.

Deprecation Notes

  • Deprecate cls keyword argument of the chimera_anticluster function.
  • Deprecate bin_packing function in favour of random_bin_packing.
  • Deprecate multi_knapsack function in favour of random_multi_knapsack.
  • Deprecate knapsack function in favour of random_knapsack.

Bug Fixes

  • QuadraticModel can now be multiplied by a number in place.
  • Fix energy calculations for integer variables with large values. See #982.
  • Make dimod.BinaryQuadraticModel a virtual subclass of dimod.core.bqm.BQM.
