Dwave Hybrid Versions Save

New Features

• Add Python 3.11 support. See https://github.com/dwavesystems/dwave-hybrid/pull/285.

Fixes

• Adapt SA concurrency test to new Neal default schedule. See https://github.com/dwavesystems/dwave-hybrid/pull/278.

• Add lattice ref solver to docs. See https://github.com/dwavesystems/dwave-hybrid/pull/282.

• Stop using deprecated numpy type aliases. See https://github.com/dwavesystems/dwave-hybrid/pull/283.

• Fix async multiprocess queue logging test. See https://github.com/dwavesystems/dwave-hybrid/pull/286.

New Features

• Add LatticeLNLS reference workflow for larger-than-QPU lattice-structured problems.

• Add LatticeLNLSSampler, a dimod-compatible hybrid decomposition sampler for problems of lattice structure.

• Add make_origin_embeddings decomposer that creates optimal embeddings for a QPU or cubic lattice.

Fixes

• Support unorderable variables in energy based decomposer (fixes #273).

Fixes

• Support all structured samplers in SubproblemCliqueEmbedder (#271)

Fixes

• Fixed State.from_sample to accept SampleSet. Fixed KerberosSampler to accept SampleSet for initial state (#268)

Upgrade Notes

• Drop Python 3.6 support (#269)

New Features

• Support dimod<0.13.0 (#266)

Fixes

• Docs refresh (#262)

New Features

• Add hybrid.Log, a block to log user-define state metrics to a JSON file, python logger, or in-memory queue or list. See #257.

• Add convenience JSON encoders for commonly used NumPy (hybrid.utils.NumpyEncoder) and Ocean types (hybrid.utils.OceanEncoder). See #257.

Fixes

• Clarify docs, #142.

Upgrade

• Drop dimod 0.8.x support. Oldest supported dimod version is now 0.9.6. See #259.

New Features

• make_origin_embeddings problem decomposing utility that creates optimal embeddings for a lattice. Embeddings are compatible with the topology and shape of D-Wave QPU samplers (https://github.com/dwavesystems/dwave-hybrid/pull/252).
• SublatticeDecomposer that produces lattice-structured subproblems (https://github.com/dwavesystems/dwave-hybrid/pull/252).

Fixes

• SteepestDescentProblemSampler now actually uses greedy.SteepestDescentSolver (https://github.com/dwavesystems/dwave-hybrid/pull/250).

Fixes

• Support dimod 0.10 (https://github.com/dwavesystems/dwave-hybrid/pull/248)

Fixes

• Added Python 3.9 support (#242)
• Docs: fixed broken links (#243)
• Hybridized samplers will now receive only accepted sampling parameters (#244)

Changes

• Dropped Python 3.5 support (#247)

New Features

• Added beta_range option to (Hybridized)PopulationAnnealing and CalculateAnnealingBetaSchedule
• ProgressBetaAlongSchedule now outputs delta_beta in addition to beta
• Made ProcessPoolExecutor availability optional to enable use on systems with process limitations

Fixes

• Expanded range of supported energies in EnergyWeightedResampler
• Linear beta schedule and better defaults in PopulationAnnealing
• Tests not included in the package anymore

Changes

• Deprecated use of beta in EnergyWeightedResampler. Use delta_beta instead.
