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 first element of the array. Then you look for the smallest element in the remaining array (an array without the first element) and...
Uninformed in this context means that the algorithm doesn't have any additional information that helps it determine where it should go. Think of it like a near-sighted person trying to navigate the streets of a city they're not familiar with. All the information they have is what...
(1) Import data with python We need package Numpy ; We need module operator 4. Steps of a simple KNN algorithm (1) We should have a training data set, a label set including labels for each training example in the training data set and a piece of new data to be classified. ...
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 ...
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 ...
Let's see how to sort a list alphabetically in Python without the sort function. We can use any popular sorting techniques like quick sort, bubble sort, or insertion sort to do it. Let's learn how to do it with Quick sort, which can be two to three times faster. The algorithm's ...
an iterative improvement algorithmbegins with a guess of a solution to an equation. It repeatedly applies anupdatefunction to improve that guess, and applies aclosecomparison to check whether the current guess is "close enough" to be considered correct. ...
Visual A* Pathfinding and Maze Generation in Python This project provides a high-performance implementation of the A* ("A-Star") pathfinding algorithm (based on this Lisp implementation by Andrew Kravchuck) along with various maze generation techniques to showcase how this algorithm works, as well...
