Enables reuse of model descriptions in the SDK with ``.. automodule::`` (currently the descriptions are sourced in both classes and /concepts), adds docstrings to C++ functions.

To match the DQM https://github.com/dwavesystems/dimod/blob/5d2043d0b662f38bd51e062367c2e4b703b457a1/dimod/discrete/discrete_quadratic_model.py#L767

Either checking the bounds in `CQM.check_feasible()` and/or adding an explicit `.check_bounds()`. See also: https://github.com/dwavesystems/dimod/issues/954

Consider making BQM.num_variables, BQM.num_interactions and BQM.shape methods rather than properties

8

Currently, `BQM.num_variables`, `BQM.num_interactions` and `BQM.shape` are all properties rather than methods. I think that it would be better to make them proper methods. Pro: * Determining `num_interactions` is an `O(num_variables)`...

Use a more uniform structure for cython classes

1

Currently we have two patterns for Cython classes and it would be nice to be more consistent #### Subclass pattern Have a Cython class as a superclass of the Python...

Support for single-binary-variable discrete variable

1

**Application** Currently ``dimod.ConstrainedQuadraticModel.add_discrete()`` rejects discrete variables with fewer than two binary variables. I think it makes sense to support a single-binary-variable discrete because that can be a use case for...

dimod.higherorder.utils.make_quadratic gives inconsistent / incorrect results

4

**Description** [D-Wave has indicated at least two approaches](https://docs.dwavesys.com/docs/latest/c_handbook_3.html) for reducing higher order terms to quadratic, namely Reduction by Substitution and Reduction by Minimum Selection. Both of these are shown to...

Display constraint weight and penalty in CQM

2

**Application** I want to be able to see whether I set a hard or soft constraint on my CQM and what value of weight & penalty fo rsoft constraints. **Proposed...
