The process described in “Implement ChromosomeToCycle” is in fact invertible, as described by the following pseudocode.

CycleToChromosome(Nodes)
     for j ← 1 to |Nodes|/2
          if Node2j−1 < Node2j
               ChromosomejNode2j /2
          else
               Chromosomej ← −Node2j−1/2
     return Chromosome
