(Prototype of a) MaxCut and BQP Instance Library
Instance Library for the Maximum Cut and the Unconstrained Binary Quadratic Optimization Problem
Instance: bqp250-7, Dataset: B
Sparse unconstrained BQP instances (density 10%) generated by John E. Beasley as part of the OR Library (1990) where they can be retrieved with weights assuming a maximization objective.
There are ten instances bqpn-i with dimension n=50,100,250,500. These instances are also part of the Biq Mac Library (2007).
