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 ...
I attached a code example and a small lp file. For the small example a value of barstartweight around 5.1 seems to give a start close to the given solution. However, for my larger lp (~350000 variables) the result stays at ||x1|| = 0.0 for barstartweight of 1, 1e4, 1e8 and 1e12.
