SoPlex start basis generation base class.SPxStarter is the virtual base class for classes generating a starter basis for the Simplex solver SoPlex. When a SPxStarter object has been loaded to a SoPlex solver, the latter will call method generate() in order to have a start basis generated. Implementations of method generate() must terminate by loading the generated basis to SoPlex. Loaded bases must be nonsingular. More...
