Multi-positional eligibility

[sansbacon]

From reviewing the code, I can't tell if the optimizer handles multi-position eligibility

I do not believe so. I looked at this in the past and ended up writing my own from scratch.

What constraints did you add? No more than 1 of a player ID?

[sansbacon]

If you add a player multiple times to the pool for different positions, you could create a constraint like this. for pid in set([p.id for p in players]): prob += sum([x[player] for player in players if player.id == pid]) <= 1

I'll look into it on weekends.

Kudos to the optimizer that was created, it really is a great solution, efficien, is very customizable, and fits my exact needs. I just wanted to second that I am still encountering this issue where a player with multiple positions will be added to the lineup as a member of both those positions.

A work around I found was adding the player twice to the pool, assigning them a unique id, then creating a constraint in the optimizer listed above (this was inserted into the optimizer function):

for pid in set([p.id for p in players]):
                prob += lpSum([x[player] for player in players if player.id == pid]) <= 1

What version of library you use? It should be fixed in latest version.

[brendanahart]

I'm running version 1.1.2 of the library and python 2.7

Can you provide info about site and sport and players list sample?
