Hi Laci,
one little change is missing in what you committed: in BCP_lp_pool.cpp, line
8, the second std::max also has to be qualified with <double>, i.e. the line
should be
_violation = std::max<double>( 0.0, std::max<double>(_row->LowerBound()-lhs,
for VC7 to compile correctly. Could you correct that?
Everything else works perfectly!
Thanks a lot,
Jörg

Thanks! I have committed your changes (with one difference: I have changed
to
using CoinCpuTime() from BCP_time_since_epoch()). Please check it out and
verify that it works correctly.
Thanks again,
