childclosint: Transform the vector into ranking for DECOR
Description
Closest integer approach is used: the elements of x are rounded
to the closest integer. Then check if any solution exists outside
of the bounds (and get it back inside the bounds randomly).
Finally repair the solution if repetitions exist.References
