Generate a binary quadratic model with random biases and offset.

Biases and offset are drawn from a uniform distribution range (low, high).

  • 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:

    • Vartype.SPIN, 'SPIN', {-1, 1}

    • Vartype.BINARY, 'BINARY', {0, 1}

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

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

  • cls – Binary quadratic model class to build from. Default is BinaryQuadraticModel.

  • seed – Random seed.
