DEFAULTALG

This selects the algorithm that will be used to solve the LP if no algorithm flag is passed to the optimization routines.

2	Dual simplex.
3	Primal simplex.
4	Newton barrier.

Please note that this will affect how the MIP node LP problems are solved during the global search. To change how the root LP is solved only, please use the appropriate flags to XPRSlpoptimize or XPRSmipoptimize.

XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
