In hamiltons formulation, a true dynamical trajectory of a system between an initial and final configuration in a specified time is found by imagining all possible trajectories that the system could conceivably take, computing the action a functional of the trajectory for each of these. In fact, maupertuis or euler principles of least action are historically the first formulation of a least action principle, but one have to wait lagrange and hamilton to have a modern version, with the socalled eulerlagrange equations, which allow us to obtain the equations of movement.
