set_floor_firstSpecifies which branch to take first in branch-and-bound algorithm. void set_floor_first(lprec *lp, short floor_first); Return Value set_floor_first has no return value. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_lp_file, read_LP, read_mps, read_MPS floor_first Specifies which branch to take first in branch-and-bound algorithm. Can by any of the following values:
Remarks The set_floor_first function specifies which branch to take first in
branch-and-bound algorithm. This can influence solving times considerably.
Depending on the model one rule can be best and for another model another rule. Example
