Quantum-Inspired Optimization for Large-Scale Combinatorial Problems
Jincheng Zhang
Abstract
Large-scale combinatorial optimization problems, arising in diverse fields such as logistics, finance, and operations research, pose a significant challenge to classical optimization algorithms. These problems typically involve searching through an exponentially large solution space, making exhaustive search methods computationally intractable. This paper proposes a novel quantum-inspired optimization algorithm designed to address this challenge. The algorithm leverages techniques inspired by amplitude estimation, a core concept in quantum computing, to accelerate the search process. Specifically, we employ a Monte Carlo-based approach that utilizes amplitude estimation to efficiently sample from the probability distribution governing the solution space. The resulting algorithm demonstrates promising performance in tackling large-scale combinatorial problems, offering a computationally efficient alternative to traditional optimization methods. We demonstrate the algorithm's effectiveness through theoretical analysis and provide insights into its advantages and limitations. The primary goal is to provide a viable method for tackling complex optimization tasks, drawing inspiration from quantum principles without the need for full quantum hardware.
