WebHere, we propose a method for generating a High Dimensional Model Representation (HDMR) of a multidimensional potential energy surface (PES) and apply it to reactive molecule–surface scattering problems. In the HDMR treatment, all N degrees of freedom (DOF) of an N-dimensional PES are represented but only n < N are explicitly coupled. WebHigh-dimensional model representation is a finite expansion for a given multivariable function. The expansion was first described by Ilya M. Sobol [1] as The method, used to …
