[Help-glpk] Structural variables initial values

[Antonello Lobianco]

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
