given a weighted, directed graph. Give an O(VE)-time algorithm to …
This is the 24.1-5 question in CLRS. I'm having a hard time understanding the questions and also how to solve it. δ(u,v) is defined as the shortest path weight from u to v if there exist a path from u to v. Let G=(V,E) be a weighted, directed graph with weight function w:E→R.
Find the minimum path to every vertex using Bellman-Ford
You are not parsing this right. The text of the exercise uses $\delta$ implicitly; traditionally $\delta(uv)$ in the context of graph theory stands for the minimum distance metric.
Find an MST in a graph with edge weights from {1,2}
The most costly part of Prim is looking for the next vertex to add: the one of the remaining vertices that has the cheapest connection to the tree already constructed. Here we only have to know whether there are still vertices that have a connection of weight 1 (because they have priority to those of weight 2).

A cut (S ,V-S) of an undirected graph G = (V,E) is a partition of V(as defined in CLRS Book) .You can think it as a line that divides graph into two disjoint sets of vertices on its either side.A cut respects a set A of edges if no edge in A crosses the cut.An edge is a light edge crossing a cut if its weight is the minimum of any edge crossing ...
