Hello,
I wonder if there are any plans for GLPK to provide an interface to the
COIN-OR CGL cut generator library in order to provide better/deeper cuts
in MIP optimization? (CGL is licensed under the CPL which is similar
to the LGPL)
In my experience the CBC solver form the COIN-OR people, which uses CGL
library to generate cuts is much faster than GLPK on MIP problems and
even solves problems GLPK fails to solve. If you need an example
problems, I can provide some.
I would prefer to use GLPK for its good support of MathProg and ease of
use (CBC can only read MPS files and has no modelling support).
Sebastian
