randint(graph: int | Tuple[Collection[Hashable], Collection[Tuple[Hashable, Hashable]]] | Collection[Tuple[Hashable, Hashable]] | Graph, vartype: Vartype | str | frozenset, low: int = 0, high: int = 1, cls: None = None, seed: int | None = None) BinaryQuadraticModel[source]#

Generate a binary quadratic model with random biases and offset.

Biases and offset are integer-valued in specified range.

  • graph – The graph to build the binary quadratic model (BQM) on. Either an integer n, interpreted as a complete graph of size n, a nodes/edges pair, a list of edges or a NetworkX graph.

  • vartype

    Variable type for the BQM. Accepted input values:

  • low – Inclusive low end of the range for the random biases.

  • high – Inclusive high end of the range for the random biases.

  • cls – Deprecated. Does nothing.

  • seed – Random seed.


A binary quadratic model.

Deprecated since version 0.10.13: The cls keyword argument will be removed in 0.12.0. It currently does nothing.
