Feature/mock d wave sampler

10

I updated the interface - sampleset format, parameters and properties to match DWaveSampler() on Advantage processors. I swapped out the neal sampler for a greedy sampler as the QPU sampler...

majority_vote introduces undocumented bias in sample set

1

**Description** dwave.embedding.chain_breaks.majority_vote() documentation error and feature request: For chains assignments such as [-1 -1 +1 +1] or [0 0 1 1] there is no majority. This function assigns all such...

Temperature feature

6

Routines are provided to efficiently establish the temperature of a Classical Boltzmann sampler from a set of samples for an arbitary Hamiltonian. This can be used to provide an estimate...

Multiple documentation pages titled 'Composites' with differnt listings

1

**Description** Two pages exist titled composites, but listing different methods that do not seem clearly delineated: https://docs.ocean.dwavesys.com/en/stable/docs_dimod/reference/sampler_composites/composites.html https://docs.ocean.dwavesys.com/en/stable/docs_system/reference/composites.html Also DWaveCliqueSampler is confusingly not a composite sampler, may be worth a...

**Description** The uniform_torque_compensation can return a chain strength of '0' which will be confusing to some users. One might imagine workflows where this creates an issue, e.g. if a user...

**Description** The behaviour of mine_clique_embeddings seems to be independent of the argument mask_bound, whereas we would expect the routine to become slower, and produce a higher quality cache (on average)...

Feature/torus

1

The primary purpose of this pull request is to provide generators for the instances evaluated in https://arxiv.org/abs/2202.03044 [BBRR]. The pull request: - Adds support for torus graph variations upon Chimera,...

**Description** draw_chimera fails with text error: /home/jraymond/PYTHON3-VENV/OCEANSDK/lib/python3.6/site-packages/dwave_networkx-0.8.8-py3.6.egg/dwave_networkx/drawing/qubit_layout.py:195: MatplotlibDeprecationWarning: Adding an axes using the same arguments as a previous axes currently reuses the earlier instance. In a future version, a new...

Conversion from flux_biases (units of Phi0) to h (unitless) and vice-versa

6

Both flux_biases and h apply time dependent longitudinal fields (fields conjugate to sigma^z in the Hamiltonian description, see documentation). At given point in the anneal s=t/t_a, h and flux_biases can...

Two enhancements: Add support for zephyr lattices on zephyr solvers (Advantage2) Improve handling of unyielded edges, improving performance for lower yield processors using dwave-ocean-sdk and networkx algorithms.
