PPT-Backtracking algorithms Outline

In this topic we will cover Traversals of trees and graphs Backtracking Backtracking Suppose a solution can be made as a result of a series of choices Each choice forms a partial solution These choices may form either a tree or DAG. You probably solved it immediately but can you describe the algorithm you use to solve it On a larger maze the actual algorithm you use would be cleare and is called backtracking This is where you try a path until you get stuck then retrace your ste Thomas H Palmer The Teachers Manual Being an Exposition of an Ef64257cient and Economical System of Education Suited to the Wants of a Free People 1840 When you come to a fork in the road take it Yogi Berra 3 Backtracking In this lecture I want to OUTLINE •Algorithms Used and Programs Available •Workflow and Strategies •MEME/MAST Demo (online and command Protein Motifs DNA Motifs MEME Output Algorithms •Enumeration •Pr snarf. the code for today’s class. . Then think about the famous 8-Queen’s Puzzle. The question is: is there a way to arrange 8 queens on a (8x8) chessboard so that no 2 queens can attack each other (queens can attack horizontally, vertically, and diagonally). Lecture . 22. : .

The object is to place queens on a chess board in such a way as no queen can capture another one in a single move. Recall that a queen can move horizontally, vertically, or diagonally an infinite distance. Instructor: Kris Hauser. http://cs.indiana.edu/~hauserk. 1. Constraint Propagation. Place a queen in a square. Remove the attacked squares from future consideration. 2. Constraint Propagation. Count the number of non-attacked squares in every row and column . Problem - a well defined task.. Sort a list of numbers.. Find a particular item in a list.. Find a winning chess move.. Algorithms. A series of precise steps, known to stop eventually, that solve a problem.. In this lesson, we will:. Describe sorting algorithms. Given an overview of existing algorithms. Describe the sorting algorithms we will learn. Sorting. Given an array that has arbitrary entries, . int array[10]{82, 25, 32, 85, 16, 36, 40, 4, 28, . The N-queens problem Team: 404 brain not found Amanda Wilder, Lukas Paradiso, & Evan Holmberg Abstract The project analyzes three different algorithms to find the best and time sensitive solution to the N-Queens problem. Computational complexity is considered to find the most efficient algorithm. 10 Bat Algorithms Xin-She Yang, Nature-Inspired Optimization Algorithms, Elsevier, 2014 The bat algorithm (BA) is a bio-inspired algorithm developed by Xin-She Yang in 2010. 10.1 Echolocation of Bats N Queens Problem by Max Groover, Chris Wehunt , Forest Gates Introduction The N - Queens problem is finding the placement of N queens on an N×N chessboard so that no two queens attack each other.
