  a>  sum over i for  [  c*(ai)^2 * bi/ (ai+x)] = 0.5  ,  can you help me
  a> to do this under optmodel?

and your perl question is? even if optmodel is some perl package (which
i never have heard of), this would be beyond the level for a beginner's
list. please find an optmodel list/forum to ask this.
