Acknowledgements

I would like to thank Chris Downing for providing the H$ _{2}$/LiO/MgO system from which the microiterative shell model optimisation tests were derived. I would also like to thank Richard Catlow, Alexey Sokol, Aron Walsh and Paul Sherwood for their help in preparing the dCSE grant proposal and Phil Ridley and Ian Bush for their suggested improvements. Thanks also to Johannes Kästner for helpful discussions about the details of the microiterative algorithms.
