TILAMBDA
TILAMBDA = real
Default: TILAMBDA = 0.0
Description: TILAMBDA defines the coupling parameter [math]\displaystyle{ \lambda }[/math] used in Thermodynamic integration using a Hessian reference. The value of [math]\displaystyle{ \lambda }[/math] must be from the inverval [math]\displaystyle{ \langle 0, 1 \rangle }[/math].
How to run thermodynamic integration calculations is given here.
