WebUsing the hill climbing algorithm, we can start to improve the locations that we assigned to the hospitals in our example. After a few transitions, we get to the following state: At this state, the cost is 11, which is an improvement over 17, the cost of the initial state. However, this is not the optimal state just yet.
