The quadratic unconstrained binary optimization problem (QUBO) is equivalent to a number of prominent combinatorial and discrete optimization problems and generalizes many others. In this chapter we will discuss the computational complexity aspects of the problem along with tractable special cases. Many of those results are derived from the related properties of the optimization problems which are equivalent to or generalized by QUBO.
