velocity_constraint {particles}

Limits particles to a specific velocity range

Description

This constraint puts bounds on the magnitude of velocity a particle can have. Particles where either end of the bound is NA ignores the constraint. If a particle with no velocity is forced to have a velocity the direction will be random.

Training parameters

The following parameters defines the training of the constraint and can be passed along a call to impose()

• v : The velocity allowed for the particle. (tidy eval)

• vmin : The lowest permissible velocity. If NULL then v will be used. (tidy eval)

• vmax : The highest permissible velocity. If NULL then v will be used. (tidy eval)
