<div class="ajy"><img class="ajz" id=":2dr" tabindex="0" src="images/cleardot.gif" alt=""></div>I
am trying to solve a problem with 54 variables and 63 equality
constraints. Several of the constraints are redundant -- so the problem
is feasible -- but finding a minimal set is nontrivial and changes
depending on the configuration.<br>
<br>When I try to solve the problem, Ipopt aborts with the error
TOO_FEW_DOFS. Writing the equality constraints as inequality constraints
-epsilon < g(x) < epsilon does allow ipopt to run and converge.<br><br>Is there a better solution?
