How to reduce memory usage by the solver?
We have a large model and it ran out of memory when it is starting concurrent solve with dual and barrier method. So is it possible to just pick one method here to reduce the memory requirement? Than...
You can use the LPFLAGS control:

You can set it to 2 for barrier or 0 for dual simplex. You can use the setControl method on an xpress problem to set the control value:
