(Prototype of a) MaxCut and BQP Instance Library
Instance Library for the Maximum Cut and the Unconstrained Binary Quadratic Optimization Problem
Instance: G_15, Dataset: HR
MaxCut instances generated by Christoph Helmberg and Franz Rendl (2000) using the machine independent graph generator ``rudy'' written by G. Rinaldi. The precise calls to ``rudy'' can be obtained from the original article.
The first 21 graphs have 800 nodes. More precisely:
G43 to G54 are again constructed using the same types.

The first 21 graphs have 800 nodes. More precisely:
- Graphs G1 to G5 are random graphs with unit weights and a density of 6%.
- G6 to G10 are the same graphs with random edge weights from {-1, 1}.
- G11 to G13 are toroidal grids with random edge weights from {-1, 1}.
- G14 to G17 are composed from the union of two (almost maximal) planar graphs with unit weights.
- G18 to G21 are the same graphs with random edge weights from {-1, 1}.
G43 to G54 are again constructed using the same types.
