Why does Xpress ignore my warm start lp solution?
I am trying to use a warm start of the newton barrier method using the example provided here. However, instead of using my supplied solution the solver starts with all values set to 0. I have tried ...
Apparently, not setting the parameter presolve=0 allows the value to change, so maybe that was the problem? However, I still do not get the point that I gave the problem as a starting point.
How does barstartweight work? I want the solver to start at the feasible point that I provide. Do I just set the value very high? Or is there a specific value I need to set it to?
