WebWe generalize this multistage procedure in the present paper. The outline of the paper is as follows. Section 2 extends the deﬁnition of separability introduced in [21] for parallel gatekeeping (k D 1) to arbitrary k; we refer to it as k-separability. Section 3 derives k-separable truncated stepwise MTPs called k-truncated MTPs.
