QUBO++ includes three QUBO/HUBO solvers: the Easy Solver, the Exhaustive Solver, and the ABS3 Solver. They support HUBO formulations of up to degree 8.

Easy Solver

• Searches for solutions to QUBO/HUBO formulations on x86_64 multicore processors.

• Multithreaded acceleration: utilizes Intel oneTBB for parallel search.

• Integer coefficients: supports coefficients of arbitrary magnitude.

Exhaustive Solver

• Enumerates all solutions to QUBO/HUBO formulations on x86_64 multicore processors.

• Optimality guaranteed: the global optimum is found and certifiable.

• Multithreaded acceleration: utilizes Intel oneTBB for parallel enumeration.

• Integer coefficients: supports coefficients of arbitrary magnitude.

ABS3 Solver

• Searches for solutions to QUBO/HUBO formulations on CUDA-enabled GPUs in x86_64 hosts.

• Supported NVIDIA architectures: SM 80, 86, 89, 90, 100, 120.

• Integer coefficients: supports 32-bit and 64-bit integer coefficients.
