Hi,
> When using writeMps with OsiCpx, the integer information is lost. Using writeLp works, but not writeMps. How do I fix this?
You remember, whether you solve the LP relaxation or the MIP before
calling writeMps?
Does it work better if you add "switchToMIP();" in the beginning of
OsiCpx::writeMps?
writeMps calls the CPLEX MPS writing function, while writeLp uses an Osi
function. That may make a difference.
