Warm starting a LP problem with PuLP and Gurobi
Concretely, I was using the following steps using PuLP with Gurobi:
Update the only constraint that changes in the LP: prob.constraints['cst_a'] += a[i-1] - a[i]
Set the initial value to all LP variables … Does that mean LP warm start does not work with PuLP and/or Gurobi?
Any other idea what I could be doing wrong? …
