Since the above (highlighted in purple) optimal solution for the LP-relaxation
of the subproblem with
does not permit fathoming (5.75 > current incumbent solution of 4, highlighted
in blue, the solution is feasible, and it is noninteger), the next step
is to branch from this node with the next variable
as the branching variable. This is accomplished by clicking on the "Branch"
button next to
in the table. |
