Discrete math problem: The length of a path between vertices u and v is the sum of the weights of its edges. A path between vertices u and v is called a shortest path if and only if it has the minimum length among all paths from u to v. Is a shortest path between two vertices in a weighted graph unique if the weights of edges are distinct? Give a proof.

Suppose that G is a graph and a and b are vertices in G such that a does not =b. Prove that if there is a walk from a to b, then there is a path from a to b. A walk in the graph is a sequence of vertices where there is an edge between each pair a_i and a_(i+1). The length of a walk is n. If a_0=a_n, ie if the walk begins and ends at the same...

Let G be a simple graph in which all vertices have degree four.

Walk along it and color the edges alternately orange and blue.
