[Help-glpk] IRR (Internal Rate of Return) using MathProg

[Noli Sicad]

Hi,

I like to incorporate IRR (Internal Rate of Return) in my report (i.e.
Report Section of my LP GLPK/MathProg model). I don't how to do this
using mathprog

Linux Journal has article in IRR and programs in Java, C and Perl. You
can download the source here.

However, I have difficulties deciphering it.

Some discussions on various methods on how to calculate IRR.

My LP model is maximizing Net Present Value (i.e. revenues / Cash
flow). Here is example of the cash flow (below).

Anybody like to have a go with this problem?

Thanks in advance.
