Purpose: The development of engineering decision support systems requires effective optimization techniques to deal with complex optimization problems such as energy management, logistics optimization, and resource management. The most popular classical optimization techniques, such as Genetic Algorithm (GA) and Particle Swarm Optimization (PSO), are often less effective in terms of optimization performance and are often likely to suffer from slow optimization speed and premature convergence to local optima when dealing with highdimensional optimization search space. The quantum-inspired optimization (QIO) techniques are an emerging class of optimization techniques that attempt to mimic some principles of quantum computing on classical computers to overcome the limitations of classical optimization techniques. The purpose of this research is to develop a quantum-inspired optimization framework to overcome the limitations of classical optimization techniques in engineering decision support systems. Method: The proposed optimization framework incorporates a probabilistic amplitude representation of solutions, rotation-based evolutionary optimization, and simulated annealing acceptance criteria. The optimization framework was tested on two optimization scenarios: a highdimensional optimization problem inspired by a Rastrigin-like function representing energy management optimization and a multi-objective optimization problem inspired by logistics optimization with the goal of minimizing transportation costs and time. The optimization performance and effectiveness of the proposed optimization framework were compared with classical optimization techniques such as GA and PSO. Findings: The proposed optimization framework outperforms traditional methods such as GA and PSO in terms of speed and quality of results. In the high-dimensional problem, the proposed framework achieved an optimal value of 38.96, which is better compared to the results of PSO, which achieved 69.42, and GA, which achieved 137.22. In the multi-objective problem, the proposed framework achieved Pareto results, which show better performance and effectiveness compared to the traditional methods. Conclusion: The optimization results indicate that the quantum-inspired optimization framework is an effective optimization tool that can be used to overcome the limitations of classical optimization techniques in engineering decision support systems. The proposed optimization framework provides a link between classical optimization techniques and emerging quantum optimization techniques while being able to run on classical computers.

Quantum-inspired optimization offers practical benefits for complex engineering decisions when fully-fledged quantum hardware is unavailable. This study introduces a quantum-inspired framework that combines a probabilistic state representation, rotation-based evolutionary updates, and a simulated annealing acceptance rule to balance global exploration and local refinement on classical hardware. The framework is assessed on synthetic but realistic case studies that emulate high-dimensional energy scheduling and a two-objective logistics design setting. On the single-objective benchmark, the proposed approach attains a substantially lower final cost and faster stabilization than conventional evolutionary baselines. On the two-objective setting, the obtained solutions populate the lower-left region of the cost–time plane, indicating favorable trade-offs. We also discuss scalability and practical deployment on commodity CPUs, and outline a path toward hybridization with emerging quantum accelerators. Validation with small-scale real data from energy scheduling and logistics is in progress and will be reported in a subsequent manuscript. Overall, the results indicate that quantum-inspired operators can provide reliable and computationally efficient decision support across diverse engineering contexts.
Quantum-inspired algorithms (QIAs) are computationally efficient algorithms that generate a quantum model in classical hardware as an alternative to the use of quantum models. In this research paper, the researchers carried out an experimental appraisal of four quantum-inspired algorithms in quantum-inspired Evolutionary Algorithm (QEA), quantum-behaved Particle Swarm Optimization (QPSO), quantum-inspired Genetic Algorithm (QIGA) and quantum Simulated Annealing (QSA) on benchmark optimization functions. The introduction of a simulation-based methodology was done in Python to test the convergence speed, global search capability, accuracy and robustness. According to the experimental findings, QPSO always performs well compared with other methods in the achievement of faster convergence and enhanced global optimality, but QEA is highly successful in cases of discrete combinatorial problems. The paper concludes that quantum-inspired models are effective in modeling the key quantum concepts like probabilistic superposition and tunneling to attain high quality optimization results with conventional computing platforms. Such results demonstrate the opportunities of QIAs as scalable pre-quantum tools of designing, AI, and industrial optimization.
Quantum computing is a big change in how to do calculations, especially good for solving complex problems that are hard for traditional computers. These problems often get worse quickly as they grow bigger, making them very difficult to solve efficiently. Although quantum computers have some big advantages, they still have some issues like limited number of qubits, noise, and problems with staying stable for long periods. To deal with these problems and make the best use of both quantum and classical methods, this research proposes a new system that mixes classical methods such as Particle Swarm Optimization (PSO) and Genetic Algorithms (GA) with quantum methods like Quantum Approximate Optimization Algorithm (QAOA) and different versions of Grover's search. [14] [15] [1] [5]The classical methods are good at finding good solutions and working reliably, while the quantum parts can help in certain tasks, like searching or improving calculations. The new system is tested on real problems in areas like logistics (like planning delivery routes), network routing (like finding the fastest paths), and job scheduling (like assigning tasks with limited resources). A way is developed to turn these problems into a form that quantum computers can understand, called QUBO. [10]The tests use real data and simulated quantum setups (like Qiskit and D-Wave Ocean SDK). The results show that this new system works better than using only classical or only quantum methods in terms of the quality of the solutions, how fast they find the answers, and how long they take. This study shows the potential of using a mix of quantum and classical methods to solve problems more effectively and sets up a foundation for future research in using quantum methods to help make better decisions.

This paper explores the application of a quantum-inspired genetic algorithm (QIGA) for solving complex optimization problems. Traditional genetic algorithms (GAs) can struggle with the intricacies of high-dimensional and non-linear problems, often encountering issues with premature convergence and local optima. This research proposes a novel approach where a standard GA is modified to incorporate principles inspired by quantum mechanics, specifically utilizing quantum-inspired concepts such as superposition and interference, to enhance the exploration and exploitation phases. The core claim is that QIGA can effectively tackle complex optimization scenarios. The mechanism involves mapping the original problem into the fitness function of the GA, and subsequently using the QIGA to perform the optimization. The results demonstrate the potential of this hybrid approach to improve solution quality and speed, particularly in problems with challenging characteristics. The research highlights a promising direction for combining classical optimization techniques with quantum-inspired ideas, offering a new tool for tackling computationally intensive optimization tasks. ---
Large-scale optimization (LSO) problems—those with hundreds to thousands of decision variables—are prevalent in engineering design, logistics, telecommunications, and machine learning hyperparameter search. Classical evolutionary algorithms often struggle in this regime due to premature convergence and prohibitive search costs. This manuscript presents a Quantum-Inspired Genetic Algorithm (QIGA) that transfers three ideas from quantum computation into a purely classical algorithm: (i) Q-bit angle encoding that maintains a compact, uncertainty-aware distribution over decision values, (ii) rotation-gate adaptation that updates search probabilities toward promising regions while preserving exploration, and (iii) quantum observation that draws diverse candidate solutions from the encoded amplitudes at each generation. We further couple the core QIGA with (a) an island-model decomposition for ultra-high dimensionality, (b) surrogate-assisted local refinement for exploitation at low cost, and (c) a feasibility-aware penalty for constraints. We evaluate the approach on five canonical continuous benchmarks in 1,000 dimensions (Sphere, Rosenbrock, Rastrigin, Ackley, Griewank) under a fixed computational budget. Across 30 independent runs per function, QIGA achieves lower final objective values and higher success rates than classical GA, PSO, and DE baselines. A non-parametric Wilcoxon signed-rank test indicates statistically significant improvements for QIGA (adjusted p < 0.01) on all functions. We analyze the algorithm’s scaling behavior, the role of angle-space step control, and the contribution of island-level diversity. The results suggest that quantum-inspired probability evolution provides a robust inductive bias for LSO by decoupling representation capacity from point estimates and by enabling distribution-aware search moves. We conclude with practical guidelines for tuning and discuss extensions to constrained and mixed-variable problems.
This paper explores the development and application of novel optimization algorithms inspired by the principles of quantum mechanics. Recognizing the potential of quantum phenomena like superposition and tunneling for enhancing computational efficiency, we propose a new algorithmic framework that mimics these behaviors within a classical computing environment. The core idea is to construct an optimization algorithm that incorporates probabilistic search strategies, analogous to quantum tunneling, and explores multiple solution possibilities concurrently, similar to superposition. This approach aims to overcome the limitations of traditional optimization methods, particularly in tackling complex, high-dimensional problems. We detail the algorithm's design, emphasizing the key mathematical formulations and probabilistic elements. The proposed algorithm's performance is evaluated through theoretical analysis and conceptual demonstrations, showcasing its potential to offer improved convergence rates and solution quality compared to established classical optimization techniques. The research contributes to the burgeoning field of quantum-inspired computing, providing a practical and accessible approach for leveraging quantum concepts for optimization challenges.
