Hello.. I have on my model many agents that need to frequently solve a
(relatively small) MIP problem.
This problem change slightly from one solve() call to to the other, so I am
wandering if I can pass the previous solved quantities as initial values.
I am currently running my simulations creating and destroying every time the
glpk problems, but I am wandering if it is best to create them only the first
time and destroy them at the end of the simulation.
If I don't destroy the glpk problems, is glpk smart enought to take advantage
of previously solved problems, even if in the maintime the structure of the
matrix is slighty changed (eg. I added a row and/or a column) ??
cheers,
Antonello
