DFS est un algorithme permettant de rechercher ou de parcourir des graphiques ou des arbres dans le sens de la profondeur. L'exécution de l'algorithme commence au nœud racine et explore chaque branche avant de revenir en arrière. Il utilise une structure de données de pile pour se s...
BFS 常用于找单一的最短路线,它的特点是 "搜到就是最优解",而 DFS 用于找所有解的问题,它的空间效率高,而且找到的不一定是最优解,必须记录并完成整个搜索,故一般情况下,深搜需要非常高效的剪枝(剪枝的概念请百度)。 PS:BFS 和 DFS 是很重要的算法,读者如果想要更深入地了解它们,建议去 OJ 或 Leetcode ...
