.. start_penaltymodel_about
One approach to solve a constraint satisfaction problem
(CSP <https://en.wikipedia.org/wiki/Constraint_satisfaction_problem>) using
an Ising model <https://en.wikipedia.org/wiki/Ising_model> or a
QUBO <https://en.wikipedia.org/wiki/Quadratic_unconstrained_binary_optimization>_,
is to map each individual constraint in the CSP to a 'small' Ising model or
QUBO. This mapping is called a penalty model.
