Binary Quadratic Models
=======================
The binary quadratic model (BQM) class encodes
Ising and quadratic unconstrained binary optimization (QUBO) models
used by samplers such as the D-Wave system.
The BQM equation,
.. math::
E(\bf{v})
= \sum_{i=1} a_i v_i
+ \sum_{i`
Introduces key concepts such as objective functions, Ising models, QUBOs, and graphs, explains
how these models are used to represent problems, and provides some simple examples.
