Dear Jérémie,

did you try with option QP_BLAND, see http://www.cgal.org/Manual/latest/doc_html/cgal_manual/QP_solver_ref/Class_Quadratic_program_pricing_strategy.html#Cross_link_anchor_311? This will be slower but free from internal looping. There is also an example in the manual that shows how to use it: http://www.cgal.org/Manual/latest/doc_html/cgal_manual/QP_solver/Chapter_main.html#sec:QP-customization-cycling

Best,
Bernd.

Hi Bernd.


Do you have any news about a potential fix? Even with the hack I described
my program can still get stuck in a loop, and there's no way to know before
calling the function if it's gonna work or hang indefinitely, so it's a bit
problematic…


Best,
Jérémie.
