Witold Jarnicki, BEIT

Topic: A robust approach to QUBO on the chimera topology



Quadratic Unconstrained Binary Optimization (QUBO) is a format in which one can express multiple combinatorial and optimization problems. We shall present a report on our analysis of one of the hardware approaches, which resulted in us creating a GPU-based reference solution that happened to outperform the original.
