An improved version of hill climbing (which is actually used practically) is to restart the whole process by selecting a random node in the search tree & again continue towards finding an optimal solution.

A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the X axis. The curve is typically sigmoidal, with the stee…
