DOI: 10.1007/jhep05(2021)108

Abstract: 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… read more here.

DOI: 10.1007/jhep12(2018)054

Abstract: A bstractWe suggest an approach for simulating theories with a sign problem that relies on optimisation of complex integration contours that are not restricted to lie along Lefschetz thimbles. To that end we consider the… read more here.

DOI: 10.1007/s00382-019-04690-8

Abstract: Future climate is typically projected using multi-model ensembles, but the ensemble mean is unlikely to be optimal if models’ skill at reproducing historical climate is not considered. Moreover, individual climate models are not independent. Here,… read more here.
