WebIf xiis binary, branching creates child problems with xi= 0 and xi= 1. If xiis continuous, typically use spatial branching to create child problems with xi≤θand xi≥θ, where θis often taken to be current value of xi. Essential to use new bound on xiin each child problem to tighten relaxation, for example through RLT constraints. 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.
