A Two-Step Warm Start Method Used for Solving Large-Scale Stochastic Mixed-Integer Problems
Berend Markhorst, Markus Leitner, Joost Berkhout +2
Two-stage stochastic programs become computationally challenging when the number of scenarios representing parameter uncertainties grows. Motivated by this, we propose the TULIP-al…
