The original version of this Article contained an error in the list numerals in the IGTD algorithm section, where,


“Otherwise, the algorithm does the following:

  1. (xxii)

    \(h_{{n^{*} }} = s\)

  2. (xxiii)

    \(e_{s} = e_{{s - 1}}\)

  3. (xxiv)

    \(\user2{k}_{s} = \user2{k}_{{s - 1}}\)

now reads:


“Otherwise, the algorithm does the following:

  1. (v)

    \(h_{{n^{*} }} = s\)

  2. (vi)

    \(e_{s} = e_{{s - 1}}\)

  3. (vii)

    \(\user2{k}_{s} = \user2{k}_{{s - 1}}\)

The original Article has been corrected.
