David, The NEOS server has moved to neos-server.org. You should be able to download a new client from there.

[NEOS Support Req #543] NEOS TSP job

I tried to submit a small problem (42 vertices) to solve the TSP problem. I clicked "submit to NEOS" and the page has said "loading" and "waiting for neos.mcs..." for over an hour. It says not to click the button more than once - does it typically take this long without any feedback? I would have expected to be taken right a way with a job number or something like that. Should I go ahead and try again? Thanks, David

Hello, I am Bonmin user on Neos. I need to suppress the intermidate solver statistics. To suppress the output I set the parameters as follow : option bonmin_options "bonmin.algorithm B-BB print_level 0 outlev 0 "; but this does not work. Can you please tell me how this can be avoided? -- regards, Hossein.

Hi Dr. Bacher, NEOS has moved, please use the new NEOS location http://www.neos-server.org. Sorry about the confusion, I'll try to change the error message from the old link.

[NEOS Support Req #539] doubt regarding file format
by Kaushik Kandakatla 11 Jun '11

11 Jun '11

Sir, I'm Kaushik Kandatla, I have a small doubt and I hope that I can get it clarified from you. I transformed a Generalised Travelling Salesman Problem (GTSP) to Travelling Salesman Problem(TSP) using an algorithm. The algorithm gives a symmetric TSP. But, the metric is not euclidean. I have the complete cost matrix. How do I make a TSPLIB format file using such data? Regards, Kaushik
