PhD Thesis Topics in Metaheuristic Inspired by Quantum Computing

A metaheuristic inspired by quantum computing is an optimization algorithm based on the principles of quantum mechanics. These algorithms aim to mimic the behavior of quantum systems to find optimal solutions to optimization problems. One of the most well-known quantum-inspired metaheuristics is the quantum-inspired evolutionary algorithm (QEA). The QEA uses a quantum-inspired representation of solutions, where each solution is represented as a quantum state. The quantum states evolve using quantum-inspired operators, such as quantum gates, to produce new candidate solutions. The best solutions are then selected for further optimization.

Another example of a quantum-inspired metaheuristic is the quantum-inspired ant colony optimization (QACO) algorithm. The QACO algorithm uses a quantum-inspired representation of solutions, where each solution is represented as a quantum state. The quantum states evolve using quantum-inspired operators, such as quantum gates, to produce new candidate solutions. The best solutions are then selected for further optimization.

Quantum-inspired metaheuristics have been applied to many optimization problems, including combinatorial optimization, global optimization, and multi-objective optimization. They effectively find high-quality solutions to problems, especially compared to traditional optimization algorithms.
