What is the difference between Topological sort and bellman-ford Algorithm ?
A) Do following for every vertex u in topological order. ..Do following for every adjacent vertex v of u if (dist[v] > dist[u] + weight(u, v)) dist[v] = dist[u] + weight(u, v ... following similar steps , so then why is the time complexity of bellman-ford O(VE) while for toplogical sort it is O(V+E) ?

How Bellman ford is dynamic programming?
What is the reason behind it? How do we find an optimal substructure and overlapping sub problems in this ? In which line of code memoization is done? BELLMAN-FORD(G,w,s) Code 1. INITIALIZE-SINGLE-SOURCE(G,s) 2. for i = 1 to |G.V|-1 3. for each edge (u,v) ∈ G.E 4. RELAX(u,v,w) ... 0 RELAX(u,v,w) 1. if v.d > u.d + w(u,v) 2. v.d = u.d + w(u,v) 3. v.pi = u

Regarding the complexity of Bellman-Ford ?
In the adjacency list implementation of Bellman Ford algorithm every edge is visited at most one time and total of |E| are present in the adjacency list. So,how can the complexity be O(VE) why can't it be O(E) .Though it has two loops on whole it will run for |E| times. ??
