Algorithm 2 Determining $r_p^{\left(t\right)}$ for chunk t.

1: if $t=1$ then 2: if r.b.s.s$\left(t\right)=$ true then 3:  $r_p^{\left(t\right)}=0$ 4: else 5:  $r_p^{\left(t\right)}=\mu -\gamma +1$ 6: end if 7: else 8: if l.b.s.s$\left(t\right)=$ true and r.b.s.s$\left(t\right)=$ true then 9:  $r_p^{\left(t\right)}=0$ 10: else if l.b.s.s$\left(t\right)=$ true and r.b.s.s$\left(t\right)=$ false then 11:  $r_p^{\left(t\right)}=\mu +1$ 12: else if l.b.s.s$\left(t\right)=$ false and r.b.s.s$\left(t\right)=$ true then 13:  $r_p^{\left(t\right)}=\mu +1$ 14: else if l.b.s.s$\left(t\right)=$ false and r.b.s.s$\left(t\right)=$ false then 15:  $r_p^{\left(t\right)}=\mu -\gamma +2$ 16: end if 17: end if
