Web3.(a)Find a graph such that every vertex has even degree but there is no Euler tour. (b)Find a disconnected graph that has an Euler tour. Solution: (a)Take a graph that is the vertex-disjoint union of two cycles. It is not connected, so there is no Euler tour. (b)The empty graph on at least 2 vertices is an example. WebSince deg v < ν 2 we remove at most ν degrees from the total degree of the graph. The average degree of the n − 1 vertex graph is then. ν n − 1 ≥ n ν − ν n − 1 = ν. More specifically, the average degree is non-decreasing. Therefore by the inductive hypothesis, there exists a subgraph of G ∖ { v } with minimum degree at least ...
