Python Forum

Hi,
I am working on a re-ranking problem, I have a big list of items, each item has two scores (x,y), I want to rank N of the items at a time such that it maximizes the average of x and y, it is ok if y decreases by p. I understand that it is an optimization problem but I don't know how to start with it. Do you suggest any algorithms and optimization package in python that might help me to implement this efficiently?

Thank you

If you don't know where to start, you need to sit down and learn python first.
