<p class="MsoNormal"><span lang="EN-US">I’m new with Ipopt and I’m trying to find good termination criteria for my optimization problem. In some cases the problem got solved with success. In other cases solving the problem exceeds maximum CPU-time, but the
results seem to be adequate. In these cases I tried to introduce the “acceptable tolerance” options. When I set the acceptable tolerances to values which get fulfilled in the optimization-run without acceptable tolerance options, the solver does not stop with
the considered “Solved to acceptable level” statement. Instead of that it exceeds again the time-limit and ends with much worse results.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is it possible that the acceptable tolerance options have an influence to the result of the optimization?<o:p></o:p></span></p>
