About finding only one optimal solution

Awaiting user input

Hi, :)

I would like to ask how to set Gurobi to stop the program when it finds an optimal solution?(and I only want to find one optimal solution, multiple optimal solutions don't make sense to me.)
I've tried setting the PoolSolutions and PoolGap parameters, but neither of them have the effect I want. :(  I'm using the python API now.

Can someone help me? Thanks in advance. :)

  By default, Gurobi stops solving when it finds an optimal solution and proves that the solution is optimal, subject to the relative and absolute optimality gaps. Are you observing different behavior? If so, can you please post Gurobi's log output?
