dimod.BinaryQuadraticModel.add_offset

BinaryQuadraticModel.add_offset(offset)

Add specified value to the offset of a binary quadratic model.

Parameters:offset (number) – Value to be added to the constant energy offset of the binary quadratic model.

Examples

This example creates an Ising model with an offset of -0.5 and then adds to it.

>>> import dimod
...
>>> bqm = dimod.BinaryQuadraticModel({0: 0.0, 1: 0.0}, {(0, 1): 0.5}, -0.5, dimod.SPIN)
>>> bqm.add_offset(1.0)
>>> bqm.offset
0.5
