Figure 4:
Restraints are included in the NCMC switching protocol. In order to keep the ligand in the binding site while the ligand’s interactions are off, an orientational restraint is used which corresponds to the dart that the ligand is in at the beginning of an NCMC move proposal. At the middle of the NCMC protocol, a MolDarting move is performed, and the restraint switches to a new orientational restraint corresponding to the new dart, which is subsequently turned off throughout the rest of the protocol.
