PyQUBO: Python Library for Mapping Combinatorial Optimization Problems to QUBO Form

We present PyQUBO, an open-source Python library for constructing quadratic unconstrained binary optimizations (QUBOs) from the objective functions and constraints of optimization problems. PyQUBO enables users to prepare QUBOs or Ising models various combinatorial problems with ease thanks abstraction expressions extensibility program. formulated using are solvable by machines, including quantum annealing machines. introduce features applications in number partitioning problem, knapsack graph coloring integer factorization a multiplier. Moreover, we demonstrate how can be applied production-scale through integration Through its flexibility use, has potential make more practical tool among researchers.
