Changes 4.32:
The following new features were included in the MIP solver
* MIP presolver
* mixed cover cut generator
* clique cut generator
* Euclidean reduction of the objective value
Due to changes the routine glp_intopt may additionally return
GLP_ENOPFS, GLP_ENODFS, and GLP_EMIPGAP.
The API routines lpx_integer are lpx_intopt are deprecated,
since they are completely superseded by glp_intopt.
The following new branch-and-cut API routines were added:
glp_ios_row_attr determine additional row attributes
glp_ios_pool_size determine current size of the cut pool
glp_ios_add_row add constraint to the cut pool
glp_ios_del_row delete constraint from the cut pool
glp_ios_clear_pool delete all constraints from the cut pool
