Meaning of MD is to follow the Newton equation with the total energy (kinetic energy plus interaction energy). However, the CG method is used to find the minimum interaction energy and kinetic energy makes no sense in CG method.

Dear QE developers and users; I'm using QE-4.3.2 and I wanna do Molecular Dynamics calculations, with Conjugate Gradient scheme... When looking to PWscf documentation (INPUT_PW) I find only the "verlet" and "langevin" algorithm for "calculation=md" !! I wanna be sure if the conjugate gradient is included (possible) or not?
