This demo compares the classical and polite algorithms.
Two simulation windows will appear.
Most likely the second one will be directly above the first.
Move it out of the way so you can see both windows.
You can use the Show Info on each to show a commentary for each algorithm.
The animation is turned off by default on this demo.
Pushing the Step Time button on either window will step the time fro both algorithms.
It is useful to compare the grantt charts for these algorithms.
Push the Gantt Chart buttons on each one two display them.
