The algorithm works by selecting the smallest unsorted item and then swapping it with the item in the next position to be filled. The selection sort works as follows: you look through the entire array for the smallest element, once you find it you swap it (the smallest element) with the ...

Solving the sliding puzzle using a basic AI algorithm. Let’s start with what I mean by an “8-Puzzle” problem. N-Puzzle or sliding puzzle is a popular puzzle that consists of N tiles where N can be 8, 15, 24, and so on. In our example N = 8. The puzzle is divided into ...

Abstract: A Star Algorithm has been widely used in motion planning problems. This article will start from a real project to help you understand the A Star programing idea. It is nice because we will use PR2 in OpenRave as an example....
On the implementation page I show PriorityQueue in Python using heapq to return the lowest value first and also in C++ using std::priority_queue configured to return the lowest value first. Also, the version of Dijkstra’s Algorithm and A* I present on this page differs from what’s in ...
