A* 搜索算法是一种用于路径查找和图遍历的高效技术，常用于游戏和地图应用中寻找最短路径。算法根据节点的 f 值（g 和 h 的总和）选择最优路径，其中 g 表示从起点到当前节点的实际代价，h 是启发式估计的剩余代价。常见启发式包括曼哈顿距离、对角线距离和欧几里得距离。尽管不总是找到最短路径，但A*算法在多种应用场景中表现出色，如塔防游戏的路径规划。
Motivation
To approximate the shortest path in real-life situations, like- in maps, games where there can be many hindrances.
We can consider a 2D Grid having several obstacles and we start from a source cell (coloured red below) to reach towards a goal cell (coloured green below)
What is A* Search Algorithm?
A* Search algorithm is one of the best and popular technique used in path-finding and graph traversals.
Why A* Search Algorithm ?
Informally speaking, A* Search algorithms, unlike other traversal techniques, it ha
