Sir,
I am in a similar situation like the author of this question. I need to sample using Latin Hypercube, a number of discrete and continuous variables whose lower and upper bounds are given.
What do you suggest is the best method to follow here?
Thanks in advance,
Rashmi

Which of these 63 combinations would you like to see allowed in a sampling? An answer commensurate with Latin hypercube sampling is not clear to me.

Unfortunately when you do rescaling based on 'lb' and 'ub' which differs on each of the six variables and when you alter them to nearby integers, that renders these distance calculations somewhat inappropriate. It isn't clear just what you are optimizing this way.
