<p dir="ltr">Dear all,</p>
<p dir="ltr">I ran an optimisation with Matlab & fmincon and it found a solution. The exitflag value returned is 2 which means "change in x was less than options.tolx (default=1e-10) and maximum constraint violation was less than options.tolcon. if i put those "optimal" points into ipopt, it continues to iterate (>3000) but the obective function does not change much. Therefore i suspect steps size are very small and thus rhe optimizer is stuck. Is there a way in ipopt to tell him to stop if step size are too small (e.g. tolx parameter)?</p>
<p dir="ltr">Many thanks for your help! </p>
