Do you mean a receptor that binds two ligands at the same time? Can you
be specific about exactly which "binding free energy" you wish to
estimate (since with multiple ligands, there are multiple binding
constants.)
If I am not misunderstanding your question, you would probably want to
estimate each binding event individually: that is, you need to estimate
the free energy differences between four states (R, RL, RL' and RLL',
where R=receptor and L,L' are two ligands).
To get from R to RLL', you go through intermediate states with just one
ligand bound.
