Raw ctypes binding to GLPK.
set_row_bnds prob
i
bnd
lb
ub
sets bounds of i-th row (constraint). If the row is not lower (upper) bounded, lb (ub) is just ignored. If the row is equality constraint (Bnd.FX), only lb
is used and ub
is ignored.
set_col_bnds prob
j
bnd
lb
ub
sets bounds of j-th col (variable). If the col is not lower (upper) bounded, lb (ub) is just ignored. If the col is equality constraint (Bnd.FX), only lb
is used and ub
is ignored.
set_obj_coef prob
j
sets the objective coefficient at j-th col (variable)
