Hi Pierre,
This is indeed an issue with TAO default tolerances.
Specifically it has to do with constraint tolerances. The default value is an
exact zero.
The problem should still work with line 89 commented out. Our default gradient
tolerance is 1e-8. In your case, commenting out line 90 is ca
Hi Pierre,
I would say the answer to that question is "no, its not expected".
We will look into fixing it. It seems like the default tolerances are being
set to zero and the result is an inability to satisfy the constraints or
gradient of the Lagrangian to that small of a tolerance.
Thanks

Hello,
If I comment line 89 and 90 of src/tao/constrained/tutorials/ex1.c from master,
the example deadlocks with a single process.
Is this expected?
Thanks,
Pierre
$ ./ex1 -tao_monitor
Constrained Problem -
Solution should be f(1,1)=-2
0 TAO, Function value: 8., Residual: 8.48528
