Decorators¶

Decorators allow for input checking and default parameter setting for algorithms.

binary_quadratic_model_sampler(which_args) Decorator to validate sampler arguments.

find_chimera_indices(G) Attempts to determine the Chimera indices of the nodes in graph G.

For the iterator versions of these functions, see the code.

`pegasus_coordinates.linear_to_nice`(r)	Convert a linear index into a 5-term nice coordinate.
`pegasus_coordinates.linear_to_pegasus`(r)	Convert a linear index into a 4-term Pegasus coordinate.
`pegasus_coordinates.nice_to_linear`(n)	Convert a 5-term nice coordinate into a linear index.
`pegasus_coordinates.nice_to_pegasus`(n)	Convert a 5-term nice coordinate into a 4-term Pegasus coordinate.
`pegasus_coordinates.pegasus_to_linear`(q)	Convert a 4-term Pegasus coordinate into a linear index.
`pegasus_coordinates.pegasus_to_nice`(p)	Convert a 4-term Pegasus coordinate to a 5-term nice coordinate.

Base exceptions and errors for D-Wave NetworkX.

All exceptions are derived from NetworkXException.

`DWaveNetworkXException`	Base class for exceptions in DWaveNetworkX.
`DWaveNetworkXMissingSampler`	Exception raised by an algorithm requiring a discrete model sampler when none is provided.
