New Features

  • Add dimod.generators.magic_square() which allows for the generation of a constrained quadratic model whose feasible solutions are normal magic squares. The function also generates magic squares of squares when passed power=2 as a keyword argument.
  • Implement version 2.0 of constrained quadratic model serialization. See ConstrainedQuadraticModel.to_file() for details.
  • Improve LP file reading by wrapping HiGHS LP file parser.
  • Add C++ ConstrainedQuadraticModel::remove_constraints_if() method.

Upgrade Notes

  • Remove the ObjectView.to_file() method.
  • Remove the ConstraintView.to_file() method.
  • Remove dimod::lp C++ namespace.
  • Drop support for Python 3.7.

Bug Fixes

  • Fix ConstrainedQuadraticModel.from_discrete_quadratic_model() incorrectly formulating the discrete constraints. This bug was
    introduced in version 0.12.7.
  • Fix dimod.generators.frustrated_loop() to correctly handle graphs with tuple labels. See #1342.
