Update: simplified...

Dear Monks,

For indexing the best values out of a fractal structure built by adding iteratively +1 to the diagonal 4 of a 4X4 square.

Output indices for $level = $max, $level = $max-1, $level = $max -2 untill some condition has been met. In my environment, this condition will be met at level 0, or 1 or 2 in most cases, so checking the indice for low levels without building too much may be faster.

When it gets to depth 8 and more, it is very long to run (hours).

I have a good feeling for nested loops, I was also thinking about PDL, which is supposed to be better to handle large data sets... I have been working this out line by line because storing those structures as is was taking way too much memory.

Thank you very much for your comments, regards.

Frank
