Chris, enlight13.mps violates the following mps standard conventions: 1) it uses LI bound type, which is non-standard; 2) the standard says that "for integer variables, the default bounds on columns are 0 and 1". Enlight13.mps does not set upper bounds for some columns (LI sets only lower bounds), so such columns are considered as binary that leads to incorrect results. For more details about the mps format please see: http://www.cenapad.unicamp.br/parque/manuais/OSL/oslweb/features/featur11.htm in particular, the topic "BOUNDS section". Thanks.
