Hello,

I have a single Cplex model managing a Multiple Flow problem, the problem is solved iteratively.

At each iteration I calculate my flow for a given product with dynamically determined capacities. For each product, at each iteration, only the second member is modified, I therefore use the dual algorithm.

I would like to recover the basis of my model when I have product X, in order to be able to start with this basis when I re-optimize the flow for the same product X, but with other capacities.

I cannot create model as much than products, because there too many products (about 5000, so it would mean 5000 models).

I use Cplex 12.1

Thanks for the help

Try the getBasisStatuses and setBasisStatuses methods of IloCplex (C++  and Java APIs).
