SOLVED :-)<br><br>I used the slightly modified generate_tape() and deallocation part of finalize_solution() of the bocop package (<a href="http://www.bocop.org">http://www.bocop.org</a>, file bocop-1.0.3-beta/new_nlp/BOCOP_Problem.cpp) .. no more valgrind errors and problem that solve indipendently from HPOFF and the number of times it is run...<br>
<br>So for anyone trying to use Ipopt/Adol-C/ColPack together they should use that version as the one in the adol-c documentation has the reported issues.<br> <br>Thanks everyone :-)<br><br>Antonello<br><br><div class="gmail_quote">

Hi,<br>
<br>
HPOFF stands for Hessian Pattern Offset<br>
<br>
it is used to merge the sparsity pattern of the target funtion<br>
with the sparsity pattern of the constraints.<br>
<div class="im"><br>

<br>
</div>Then you have probably really large problems ;-)<br>
<div class="im"><br>

<br>
</div>So it has been a while since I programmed it. Therefore, if I remeber it<br>
right, the following should be true:<br>
<br>
One could use in the allocation<br>
<br>
instead of<br>
<br>
(HP_g[i][0]+HPOFF)<br>
<br>
probably<br>
<br>
(HP_g[i][0]+HP_f[i][0]+1)<br>
<br>
this should provide enough space but might be<br>
a considerable overestimation.<br>
<br>
