I see there is no comment for my code...
Just a thought, wouldn't be nice if someone would convert LISP into some faster language... I mean - this is TSP problem, so it needs boosting in speed of calculations... However I am not educated in other than LISP... Maybe if Daniel could see it, or Gilles (.NET)... But I need it for A2018, so maybe I am old with my wishes, but that's the problem with other languages (ObjectARX, C#, ... )... It would be the best if it could work faster than LISP, but compatible with all AutoCAD releases...
This is just my thought, no one replied, so I had to step in again...
Thanks for attention, M.R.
[EDIT : If someone succeds to translate LISP, just don't give some stupid command names for execution like : "DOIT", "TEST", ... It would be nice something like : "TSP-2D-LSP-CONVERTED" or similar...]
