Recommendation: Has Potential.
Description: This applet has a collection of sorts, including quadratic sorts, quicksort, heapsort, shellsort, shaker sort. The user selects an algorithm to use and specifies the number of items-the default is 25. If the GO button is pressed the items are sorted using the algorithm. The visualization can be slowed down or sped up with a slider control. The pause button will stop the algorithm. The Step button is used to step through movements the algorithm is doing. The abort button stops the visualization.
Evaluation: Standard bar-swapping presentation. User can watch it animate, or step through. The layout of this program is nice. The graphics are well done, and it has a great color scheme. No response is required of the user. The program does not present any questions to the user. In animation mode, the algorithm runs through quickly at default speed. If there is a small number of items to sort, it is difficult to determine what the algorithm is doing.
