Quantum-inspired optimization algorithms are a class of computational strategies that leverage principles from quantum mechanics—such as superposition and entanglement—to solve complex optimization problems using classical hardware. Notable examples include simulated annealing, which mimics thermal fluctuations to escape local minima, and tensor network techniques, which efficiently represent and manipulate high-dimensional data structures. These approaches aim to approximate or emulate the advantages of quantum computing without requiring quantum hardware, providing powerful tools for tackling combinatorial, logistical, and machine learning challenges.
