We next compare the structural features of the ensembles we generate. The radial distribution function of all atomic interactions for each stoichiometry in figure Figure : Radial Distributions of all atomic interactions produced by pyGlobOpt runs for Pt 13 , Pt 13 H 2 , and Pt 13 H 4 using ONETEP as the energy evaluator. The radial distributions are computed for ensembles weighted by there thermodynamic presence at different temperatures, at 0 K no weighting and the ensembles will consist of exclusively the GM, at the infinite temperature limit all structures within the ensemble will have equal weighting. Each ensemble was produced using a two runs of pyGlobOpt with and without tuned settings section 3.3.5.
