خوارزميات الرسوم البيانية
تنقّل عبر خوارزميات الرسوم البيانية خطوة بخطوة وشاهد كيف تجتاز العُقد والحواف.
Depth-First SearchWatch DFS dive as deep as it can down each branch before backtracking.Breadth-First SearchSee BFS explore a graph level by level, nearest nodes first.Topological SortWatch a DAG get linearized so every edge points forward in the order.Dijkstra's AlgorithmSee Dijkstra settle the nearest node each step to find shortest paths.Bellman-Ford AlgorithmSee Bellman-Ford relax every edge each pass to find shortest paths.Kruskal's AlgorithmWatch Kruskal add the cheapest edges that never form a cycle.Prim's AlgorithmSee Prim grow a spanning tree by adding the cheapest crossing edge.
