If you take the travelling salesman problem, you can dramatically simplify the problem by constraining the salesman to visit all of the cities within the same state sequentially.
Similarly, you can reduce the complexity of routing calculations by applying some constraints. You will potentially lose the possibility of an optimal solution, but you will gain a far faster compilation time. As always with engineering, it's a trade-off.
