Status:
instance can be solved within an hour with a general-purpose solver (to a final gap of at least 0.1%)
instance has been solved (to a final gap of at least 0.1%, possibly by a problem-specific algorithm)
optimal solution to instance is unknown

Classification: A|BC|D where
A is problem type: c (convex) or nc (nonconvex),
B is type of linear variables (i.e. only appearing in linear terms): b (only binary), i (only binary or general integers), c (also continuous), or 0 if none
C is type of nonlinear variables (i.e. appearing in nonlinear terms): b (only binary), i (only binary or general integers), c (also continuous), or 0 if none, and
D is maximum degree of the polynomials.
