This document provides information about the QUBO++ Library and related APIs.
- QUBO++ Library: A C++ library that generates QUBO expressions (or quadratic polynomials) by manipulating variables and formulas.
- The library includes the following solvers and APIs:
- QUBO++ Easy Solver with API : A basic QUBO solver running on a CPU, developed for testing, evaluation, and learning purposes.
- QUBO++ Exhaustive Solver with API : A straightforward QUBO solver running on a CPU, which searches all solutions to find all optimal solutions. This solver also aims for testing, and debugging purposes.
- ABS2 GPU QUBO Solver with API : A QUBO solver running on a Linux machine with single or multiple GPUs, which can be used only for non-commercial, testing, and research purposes.
- Gurobi Optimizer Access API : An API for utilizing the Gurobi Optimizer to solve QUBO problems through the QUBO++ library. Since the Gurobi Optimizer is a commercial MIP solver, an appropriate license is required to use it. Please see https://www.gurobi.com/ for details.
