Struct GoalDistanceTransform

Source

pub struct GoalDistanceTransform {
    pub scale: f64,
    pub goal_start: usize,
    pub goal_dim: usize,
}

Expand description

Goal-distance reward transform.

Computes phi(s) = -scale * ||s[goal_slice] - goal|| and applies PBRS. Expects extras to contain "phi_current" and "phi_next" entries pre-computed via compute_goal_distance_potentials.
