  The Social Force Model is one of the most prominent models of pedestrian
dynamics. As such naturally much discussion and criticism has spawned around
it, some of which concerns the existence of oscillations in the movement of
pedestrians. This contribution is investigating under which circumstances,
parameter choices, and model variants oscillations do occur and how this can be
prevented. It is shown that oscillations can be excluded if the model
parameters fulfill certain relations. The fact that with some parameter choices
oscillations occur and with some not is exploited to verify a specific computer
implementation of the model.
