Smart Stop Condition

Smart Stop is a heuristic which reasons that no further improvements are likely to be made to the layout for the time invested and stops the process.

The purpose of Smart Stop is to save time when further improvements are very unlikely.

In the following example Smart Stop is expected to stop the process well before the 150s timeout as there are no further improvements after T=5.4s.

In the following example Smart Stop is expected to stop the process before the 300s timeout, improvements are made until the 300s mark is reached.
