  • keywords SQP added
  • status changed from new to closed
  • resolution set to fixed
  • milestone changed from not defined to openturns-0.12.2

The bug is in the run() method of SQP algorithm. The currentPoint_ attribute is initialized to the correct value after its dimension is used to build internal structures of the algorithm. The bug is solved in branch lebrun.

PS: Be aware of the fact that in your script, the SQP algorithm stops not because it has found a design point, but because it was unable to make further progress in its search.
