<div dir="ltr"><div>I'm interested in trying out TAO IPM for constrained optimization with inequality, equality and bound constraints. I implemented a test case based on the <a href="http://www.mcs.anl.gov/petsc/petsc-current/src/tao/constrained/examples/tutorials/toy.c.html">"toy example"</a> and it works well.</div><div><br></div><div>But I noticed the following comment in the <a href="http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Tao/TAOIPM.html">documentation</a>:</div><div>"This algorithm is more of a place-holder for future constrained optimization algorithms and should not yet be used for large problems or production code."</div><div><br></div><div>So I was wondering what the status of this is? Is there anything that specifically doesn't work, or is it just not production-ready at this stage? (I didn't see any documentation about IPM in the TAO manual, so I figured I'd ask here).<div><div><div class="gmail_signature"><div><span style="color:rgb(0,0,0);font-family:Calibri,sans-serif;font-size:12px"></span></div></div></div>
</div></div><div><br></div><div>If IPM isn't recommended at this stage, is there anything else in TAO that works for generally constrained problems?</div><div><br></div><div>Thanks,</div><div>David</div><div><br></div></div>
