Multiple Lineups from Pool fantasy_basketball_1_2

[Owen-Slater]

Hello, This is a really great and detailed example of how to use gurobi to solve fantasy sports problems. I actually play draftkings , and have been trying to teach myself how to optimize using gurobi opti... Anyway, I have been attempting to use PoolSolutions to return the other solutions... example:

m.setObjective(obj, sense= GRB.MAXIMIZE)
m.setParam(GRB.Param.PoolSolutions, 500) ## finds 500 best lineups
m.setParam(GRB.Param.PoolSearchMode, 2) ## makes sure these are the best solutions (2)
m.update()

m.optimize()
nSolutions = m.SolCount
print('Number of solutions found: ' + str(nSolutions))
for e in range(nSolutions):
    m.setParam(GRB.Param.SolutionNumber, e)

    for v in m.getVars():
        if v.xN ==1:   ### Help I'm stuck

..... How would I modify your colab notebook to print and save all 500 lineups. I have tried for hours, but just don't have a deep enough understanding of the syntax with gurobi and also creating the correct df calls for this. This isn't an issue, as much as a question . Thanks so much in advance, as I know there's no benefit to you helping me. Again, great work and thank you for sharing on github.

Thanks for the positive feedback. The Xn attribute is for the model, try m.Xn instead of v.Xn
