(Prototype of a) MaxCut and BQP Instance Library
Instance Library for the Maximum Cut and the Unconstrained Binary Quadratic Optimization Problem
Instance: be250.9, Dataset: BE
Unconstrained BQP instances generated by Alain Billionnet and Sourour Elloumi (2007) using the generator proposed by P. M. Pardalos and G. P. Rodgers (1990). The precise calls to the generator can be obtained from here.
