TITLE Intermolecular scoring function (without SOLVATION, indexed VDW)

# Constant scoring function
# Represents loss of translation, rotational entropy of ligand
# DM 14 June 2006 - also calculates solvent penalty for all enabled solvent
# SOLVENT_PENALTY is defined as a fraction of the ligand binding penalty
# i.e. ligand binding penalty = 1.0 * WEIGHT
# solvent binding penalty = N(enabled solvent) * SOLVENT_PENALTY * WEIGHT
# 0.37 * 5.4 = 2.0 kJ/mol, which corresponds to GOLD Chemscore penalty
# Verdonk et al, J. Med. Chem. 2005 (48) 6504-6515
