March 15, 2023 — 10. State-Space Search: Breadth-first Search. Blind search algorithms use no information about state spaces apart from the black box interface. They are also called uninformed search algorithms. diferent variants and optimizations (⇝ later) Use a closed list?

Given a graph, we can use the O(V+E) DFS (Depth-First Search) or BFS (Breadth-First Search) algorithm to traverse the graph and explore the features/properties of the graph.

In order to find the best algorithm that can solve the captured maze image, three types of graph theory algorithms are implemented and tested which are Breadth First Search , Best First...

A search algorithm is complete if it finds a solution whenever one exists [What about the case when no solution exists?] Optimality A search algorithm is optimal if it returns a minimum-cost path whenever a solution exists Complexity It measures the time and amount of memory required by the algorithm

search) space complexity: memory requirements Blind Search Algorithms We discuss six algorithms for blind search. Generally, we use a queue formulation of the algorithms. First a few denitions: : branching factor (or average branching factor); number of successors to any node : minimum solution depth in search tree : maximum depth of search tree 2

Generic Search Algorithm. Search. insert ( start, operations, isGoal): path. L= make-queue( start) loop. n:= pop( L) if [ isGoal(n)] return( n) S:= successors( n, operators) L:= insert ( S, L) until Lis empty. return( failure ) insert could be queue, stack, . . . defines strategy!

A search algorithm receives an input problem and returns a sequence of actions that leads to the solution. Example: given a maze in 2D grid and an initial position, find a path in the maze that leads to an exit.

Breadth-first search (BFS) starts and processes all nodes that are direct neighbours of starting node. Then it processes all direct neighbours of direct neighbours of starting nodes (excluding the ones already processed) and so on. The visualization below shows the BFS algorithm in action. int main() { cout << "coming soon..."; 2.

This is because we can implement a breadth first search by using a queuing function that adds expanded nodes to the end of the queue. Therefore, we could implement a breadth-first search using the following algorithm. Function BREADTH-FIRST-SEARCH(problem) returns a solution or failure Return GENERAL-SEARCH(problem, ENQUEUE-AT-END)
