Abstract

This paper explores the potential of quantum-inspired algorithms for graph search problems. Traditional random walk approaches often suffer from inefficiencies, particularly in complex graphs. We propose a novel framework that leverages concepts from quantum walks – specifically interference and tunneling – within a classical computational environment. Our algorithms dynamically adjust the probability distribution of node visits based on graph connectivity and the history of previous steps, mimicking the probabilistic nature of quantum mechanics. We demonstrate that this approach can, in certain scenarios, outperform standard random walks, offering a more adaptable and potentially faster search strategy. The core of the method lies in approximating the quantum effects through carefully designed classical simulations, without requiring actual quantum hardware. We present a mathematical formulation of the core algorithm and discuss its key parameters, focusing on the balance between classical simulation fidelity and computational cost. The results suggest a promising direction for graph search optimization, drawing inspiration from the principles of quantum mechanics.

Quantum-Inspired Random Walk Algorithms for Global Optimization

Jincheng Zhang

This paper investigates the application of quantum-inspired concepts to enhance the performance of random walk algorithms, specifically within the domain of global optimization. Classical random walk algorithms frequently struggle with convergence issues, frequently becoming trapped within local optima, a significant limitation when dealing with complex, high-dimensional search spaces. This research proposes a novel approach where random walk behavior is modeled based on principles derived from quantum mechanics, incorporating superposition and interference effects to facilitate more extensive and efficient exploration of the solution landscape. The core idea is to replace the deterministic step size in traditional random walks with a probabilistic movement governed by a quantum-like probability distribution. We explore the mathematical formulation of this process, detailing the probabilities of transition between states and the impact of interference. The resulting algorithms demonstrate improved convergence rates and a reduced tendency to get stuck in local optima compared to standard random walk methods. The paper concludes by outlining potential future research directions, including adaptive parameter tuning and integration with other optimization techniques.
