Thank you Michael, I already did, I realized immediately it was a typing error. I have to double thank you because you made me understand a thing in which I was stuck.
About the upper bound, I realized the bins could't have been enough, so my first code was a greedy solution: 1 bin per 1 item. I think this could be largely improved, as you showed me, but I still have to analyze to fully understand your suggestion. Do you think I should write the full bpp with types, code? Maybe it could help someone.
