Abstract
Optimisation problems are ubiquitous in particle and astrophysics, and involve locating the optimum of a complicated function of many parameters that may be computationally expensive to evaluate. We describe a number of global optimisation algorithms that are not yet widely used in particle astrophysics, benchmark them against random sampling and existing techniques, and perform a detailed comparison of their performance on a range of test functions. These include four analytic test…

Quantum Optimisation of Complex Systems with a Quantum Annealer

- PhysicsArXiv
- 2021

An in-depth comparison of quantum annealer with several classical optimisation techniques, namely thermal annealing, Nelder-Mead, and gradient descent, finds the general behaviour that Nelder -Mead and gradients descent methods are very susceptible to becoming trapped in false minima, while the thermalAnneal method is somewhat better at discovering the true minimum.
