This pattern is true for every parent node and every child node and this pattern can use any number of n. For every first-child: Move(Parent disc - 1, Parent Source, Parent Auxiliary, Parent Destination).įor every second-child: Move(Parent disc- 1, Parent Auxiliary, Parent Destination, Parent Source). Step 1: We make our first move by taking the first disk (the smallest one) from peg one and move it to. (a) Propose a state representation for the problem. In this problem, we will formulate the Towers of Hanoi as a search problem. The Hanoi Towers Lite The Hanoi Towers also known as Towers of Hanoi, Tower of Brahma and Lucas' Tower, it's a puzzle with a mathematical solution consisting in three rods with a number of disks of scaled sizes from bigger to smaller, the smallest at the top like a conical shape. Then move the third disc from A to C, and finally move the two disc stack from B to C. The goal is to move all the discs to the rightmost peg (see the figure above). which means for our first children we are taking 2 (3–1) as a number of discs and A is source pile C is destination pile and B is an Auxiliary pile and our second children we taking 2 is number of discs C is a Source pile, B is a Destination pile and A is an Auxiliary pile. Suppose that we want to move the disks to the third peg. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. For the first node where Move(3, A, B, C) has another two children Move(2, A, C, B) and Move(2, C, B, A). We are using here a common pattern for every Parent Pile. The first argument refers to the number of discs second refer to our Source pile, third refer to Destination pile and four refer to Auxiliary pile. The Move function can take four arguments. which every level indicated a move from source to the destination where Move is a function. ![]() Sort the white disc from the left to center post (1 move). Thus the bottom disk must make at least 2 moves. Uncover the white disc on the left post by moving the top four discs of the stack to the right post (24 1 moves). ![]() The object of the game is to move all of the discs to another peg. There are three pegs, and on the first peg is a stack of discs of different sizes, arranged in order of descending size. Before getting started, let’s talk about what the Tower of Hanoi problem is. It can't do so in one move, so it must first move from peg 1 to peg 2 and then move from peg 2 to peg 3. In this problem, you will be working on a famous mathematical puzzle called The Tower of Hanoi. If you see in the above picture then you will see I drew a tree for n = 3. To accomplish a move of n disks from peg 1 to peg 3, the bottom disk will eventually have to move from peg 1 to peg 3.
