Dear Osi,
This mail just to highlight somthing that look like a conflit between
the Cplex implementation of the Osi interface and
the OsiSolverInterface::convertSenseToBound.
It seems that for Osi
sense = R
rhs = 15
rngvalue = 10
means:
[5, 15] for Osi
and
[15, 25] for Cplex implementation of Osi.
It seems that for Osi
sense = R
rhs = 15
rngvalue = -10
means:
[25, 15] for Osi (look a bit strange as interval)
and
[5, 15] for Cplex implementation of Osi.
Should we fix something?
And is so in which direction. My opinion as a frequent user of Cplex is to
go in the direction of changing the convertSenseToBound function but I want
to listen about the other user before submitting a patch.
Vivian.
