X-Score is a "scoring function", which has its major applications to structure-based drug design studies. It computes a binding score for a given protein-ligand complex structure, and this binding score correlates to experimental binding constants well. Three individual empirical scoring functions have been implemented in this program, which are named as HPScore, HMScore, and HSScore, respectively. [user manual]
