Temat: Software aided approach for constrained optimization based on QAOA modifications
In this talk, we will present the novel approach to the constrained combinatorial problems. In particular, two modifications of the Quantum Approximation Optimization Algorithm (QAOA) will be presented – Weight-Free QAOA and Hyper QAOA . The presentation will also include dedicated QHyper framework used for performance evaluation . Furthermore, the Basin-hopping global optimization method will be compared to a simple Random Search technique. Presented modifications used for solving Knapsack Problem demonstrated better performance than the regular QAOA, suggesting their potential in addressing other kinds of problems – characterized by the delicate balance between the cost function and constraints.
