<br>
I'm optimizing some quadratic programming problem using Ipopt. It works fast :)<br>
It's known that all data is obtained from physical measurements that have precision 1e-4.<br>
Is it possible to set some parameter in Ipopt to make it working faster according to this information?<br>
<br>
Maybe I should multiply all values by 10000 and say that they are integers? Will this help to make it faster?<br>
<br>
