 where $\alpha$ is a scaling factor, $\beta$ a constant offset, $l_{i}\,x_{i}$ are the linear terms and $q_{i, j}\,x_{i}\,x_{j}$ the quadratic ones.

+We defined our problems to follow a minimization sense by default.
+While the scaling factor $\alpha$ is strictly positive in **BQPJSON**, $\alpha < 0$ can be used to indicate _maximixation_ problems using **QUBOTools**.
