Each node represents a possible location or state, while each edge signifies a valid transition between locations, often assigned a weight representing the cost of traversal. The node is then marked as "visited," meaning its shortest path is finalized.

The environment is abstracted into a graph composed of nodes (or vertices) and edges (the connections between them). From guiding characters through sprawling open-world video games to optimizing the delivery routes of global logistics networks, these systematic methods solve a fundamental problem: how to traverse a graph or grid from a starting point to a destination in the most efficient manner.
This "greedy" approach to expanding the closest frontier ensures that once a node is visited, the shortest path to it has been found, making it robust and reliable for static environments. The heuristic is the key to its intelligence; for it to guarantee the shortest path, it must be admissible, meaning it never overestimates the true cost to the goal.
