[Ipopt] round(x,n) in objective function

[Novalio Daratha]

Dear All,

I am a new user of AMPL and IPOPT. When my objective function contains

      round(x,n),

ipopt crashes with:

      exit code 3221225477

Does this mean Ipopt can not handle this in objective function? Is there an
alternative way of getting the same result?

Sincerely Yours,


Novalio Daratha
