Specifies if the objective is in the matrix or not.
void set_obj_in_basis(lprec *lp, unsigned char obj_in_basis);
set_obj_in_basis has no return value.
TRUE or FALSE. Objective is in matrix or not.
The set_obj_in_basis function specifies if the objective is in the matrix or not.
By default, the objective function is stored as the top row in the constraint matrix When this function is called with obj_in_basis = FALSE then it is moved out into separate storage. When out of the basis, the computation of reduced costs is somewhat slower. In the late versions of v5.5, there is now the option to calculate reduced cost in the textbook way, i.e. completely independently of the basis.
