Geometric interpretation of stretched mappings. In both figures, the deletion start is represented on the x-axis, and the deletion end on the y-axis. (a) The coordinates for three possible deletions A, B, and C are shown exemplarily. Assuming that deletion A corresponds to the left-most and smallest possible deletion, B to the right-most, and C to the left-most and largest possible deletion, these span a trapezoid (shown in gray) which defines the coordinates of all allowed deletions, as introduced by Sindi et al. [22]. (b) Instead of assuming a smallest and largest deletion size, a probability for the deletion size and thus for the deletion coordinates is considered, represented by the shaded gray.
