In this problem,"+ " a set of discs are to be moved from one peg to another while observing"+ " the following 4 rules:\n(1) Only one disc can be moved at a time, "+ "(2) A larger disc can't be placed on top of a smaller one, (3) Auxiliary" +" pegs may be used for the temporary placement of the discs, and (4) The" +" task should be completed in a minimum number of moves.\n\nOn a 4k "+ "screen, this applet can display up to 85 discs x 20 pegs (where the "+ "dimensions are maximized in Windows 10). It can also print the moves" +" for up to\n1000 discs x 100 pegs. The applet can handle up to 20 "+ "rotating colors for both the discs and the pegs; the initial and final "+ "pegs are displayed in green and red. The discs are displayed either "+ "round or sharp. When the applet is paused, the move button can be used"+ " to step through the moves.\n\nThe traditional version of the Towers of"+ " Chicago makes use of only 3 pegs: the initial peg, the final peg, and"+ " 1 auxiliary peg. However, the multipeg version makes use of any number" +" of pegs: the initial peg, the final peg, and 2 or more auxiliary "+ "pegs. As the number of pegs is increased, while keeping the number of "+ "discs constant, the number of moves required usually decreases.\n\nThe "+ "optimal solution for the n disc by 3 peg problem is well known: "+ "recursively move n-1 discs from the initial peg to the auxiliary peg, "+ "then move the remaining disc to the final peg, then move the first n-1 "+ "discs from the auxiliary peg to the final peg. This algorithm results "+ "in 2^n-1 moves.\n\nThe presumed optimal Frame-Stewart algorithm that "+ "this program uses for n discs and p pegs is as follows: recursively "+ "move k discs from the initial peg to an available auxiliary peg using "+ "the p peg subalgorithm, then move the remaining n-k discs from the "+ "initial peg to the final peg using the p-1 peg subalgorithm, then move "+ "the first k discs from the auxiliary peg to the final peg using the p "+ "peg subalgorithm. Dynamic programming is used to find the k values. "+ "The k values are calculated to make the number of moves minimal.\n\n"+ "This program can find different optimal solutions for each combination "+ "of discs and pegs (where pegs are greater than 3). This is accomplished" +" through 2 kinds of randomization, Scramble k Values and Scramble "+ "Discs. Each of these uses a random number seed (an integer from 0 to "+ "999). Scramble k Values uses a different k value for each recursive " +"instance of a particular subalgorithm; if this isn't selected, the " +"Random k Seed sets constant k values for each subalgorithm.
