It is required for the robot to learn the path, and exhibit a good decision making capability in order to navigate the path successfully without human' assistance. In this project, an Artificial Intelligence (AI) based algorithm called Recursive Backtracking Depth First Search (RBDS) is proposed...

Depth first search is a graph search algorithm that starts at one node and uses recursion to travel as deeply down a path of neighboring nodes as possible, before coming back up and trying other paths. const {createQueue} = require('./queue');functioncreateNode(key) { let children=[];re...
ILS is based on a simple principle that has been applied also in other heuristics such as the iterated Lin–Kernigham heuristic for the TSP (Johnson, 1990) and the adaptive tabú search for the quadratic assignment problem (Talbi, Hafidi, & Geib, 1998). First, a local search is applied ...
The algorithm’s complexity will likely be proportional to the loop with the most depth. There are problems for which the combinations of all items need to be calculated, not just the loops, such as in the notorious traveling salesman problem. In this situation, adding another input increases ...
Improving the quality of medical images is crucial for accurate clinical diagnosis; however, medical images are often disrupted by various types of noise, posing challenges to the reliability and diagnostic accuracy of the images. This study aims to enha
In PostIandII, I have introduced some basics of AI game-playing algorithms, and Monte Carlo Tree Search (MCTS) [1], a popular algorithm suitable for solving perfect information games. InPart III, which is this post, I will introduce Counterfactual Regret Minimization (CFR) [2], a popular...
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...
Default parameters start on line 278 of (models/AM_Former.py), with explanations starting on line 303: - `dim`: The dimension of features, i.e., the `dim` in `bs * num_cate * dim`. - `depth`: The number of layers of the transformer in the model. - `heads`: The number of ...
