WebIf we were to solve this with variable branching, each branch would be akin to saying something like "nurse 1,543 can/cannot work shift 16,325". Each branch in this instance has only a minor effect on the overall soution. Instead, we can use constraint branching, which allows us to make many changes at each branch. WebJan 1, 2011 · A branching decision is stated as a constraint, which will be added to the subproblem (its negation will be added to the other subproblem in case of a binary branching decision). For example, for a variable x with v ∈ D(x), we can branch on the constraint (x = v) versus (x≠v). This corresponds to the traditional enumeration of …
