A* Search Algorithm Visualization - Heuristic and Path Cost Example #1730667 (License: Personal Use)

This diagram illustrates the A* pathfinding algorithm on a directed weighted graph with six nodes (including start orange and goal blue nodes). Each node displays its heuristic estimate h(n), while edges show traversal costs; f-values like f(a)=1.5+4 are computed as g(n)+h(n). The arrow highlights the evaluation of node a and d during search expansion.

Used in AI and computer science educational content to explain informed search strategies; ideal for tutorials, lecture slides, or algorithm reference pages where users seek to understand heuristic-based path optimization.
