CVSROOT: /cvs/ppl Module name: ppl Branch: simplex Changes by: bagnara@cs.unipr.it 2006-04-18 22:33:06
Modified files: src : LP_Problem.cc
Log message: Improved LP_Problem::steepest_edge_entering_index() by avoiding duplicate computation and mitigating a problem (still present) whereby no caution is taken with respect to the possibility that mpq_class::get_d() (and, previously, also mpz_class::get_d()) give rise to undefined behavior. Added a FIXME not to forget about this problem.
