Hi Michael,

I'm not sure if this is helpful, but there is a short tutorial on Ipopt, 
which in Section 5 has a short summary of the algorithm in Ipopt. The 
URL to this report is http://drops.dagstuhl.de/opus/volltexte/2009/2089/

Other than that, for more detail you can look at the Ipopt paper listed 
on the Ipopt home page.
