People interested in the most effective methods for improving quantum optimization algorithms should read the excellent compendium of methods in
Using a quantum computer to solve a real-world problem -- what can be achieved today? by Robert Cumming and Tim Thomas, 62 pages https://doi.org/10.48550/arXiv.2211.13080 They apply - QAOA (Quantum Approximate Optimization Algorithm by Farhi in 2014 or Quantum Alternating Operator Ansatz by Hadfield in 2017) - VQE (Variational Quantum Eigensolver by Peruzzo in 2013) - Quantum Annealing (D-Wave in 2011) to variations of ambulance logistic problems. These facilities location problems are forms of the NP-Hard set cover problem and relate to how to allocate resources to fight forest fires in New Mexico. -Roger
