Please help with the problem below. Let G be a graph. Say that G is weakly Eulerian if G has an open Eulerian tour; that is, if G has a trail which contains every edge but the trail begins and ends at different vertices. Please characterize weakly Eulerian graphs. This entails ending a necessary condition which is also sufficient and proving that condition is sufficient and necessary. Solution you please refer this link!!!!!!!!!! http://arno.uvt.nl/show.cgi?fid=30031 GOOD LUCK!!!!!!!!!.
