Hi, I spent some time looking at the code, and I believe that you are correct. It should be dimension and not i that is replaced. I have corrected the error and committed to the Git repository. http://github.com/gpampara/cilib/commit/3575d8cdc4cc839f70670aab2ca26ee111604edc Kind regards, Gary lab...@gm... wrote: > Yes, that works but it seems to me that there is a bug in the dimension > that is set.
