[NEOS Support Req #508] IPOPT in NEOS
by Sofia Rodrigues 22 Oct '10

22 Oct '10

Dear professor Jeff , I'm trying to submit, for two weeks, an AMPL model in NEOS server using the IPOPT. But Neos server gives us always the following message: "No stations available for solver nco:Ipopt:AMPL. Solver administrator has been notified." Would you mind helping me in this situation?
