Such an investigation involves stochastic methods like simulated annealing that can be used if and only if the resonant field computation time is low. Fortunately, a quad–double arithmetic recurrence formula allows to compute round-trip operators faster than any adaptative numerical integrator with the same accuracy. %G English %L cea-00324595 %U https://cea.hal.science/cea-00324595 %~ CEA %~ CNRS %~ INSA-ROUEN %~ COMUE-NORMANDIE %~ IRAMIS-CIMAP %~ UNIROUEN %~ ENSICAEN %~ UNICAEN %~ INSA-GROUPE %~ CIMAP %~ OML-CIMAP %~ IRAMIS
