[Coin-ipopt] Checking number of function evaluations

[Karsten Theissen]

Dear Andreas and all other IPOPT-Users,

in my AMPL-Code, I define a function f

var f  {i in ZEIT} = ..... ;

which only occurs in the constraint:

s.t. minmax {i in AZEIT} : f[i] <= zeta;

Because the computation of f cost a lot of time, I would like to know, how 
many times this function is being evaluated by IPOPT. Is this possible by 
AMPL or directly with IPOPT ???

Yours Karsten

P.S at Andreas: IPOPT scheint in der Optimale-Steuerungs-Familie immer beliebter 
zu werden, allerdings haben die Leute große Probleme an AMPL zu kommen. Hast 
du da vielleicht einen Tipp, wo man das kaufen kann (oder kennst gar eine 
Alternative).
