The problem seems similar to Hamiltonian Path which is NP complete problem for a general graph. Fortunately, we can find whether a given graph has a Eulerian Path or not in polynomial time. In fact, we can find it in O (V+E) time. brass statue shops in mumbaiWebThe TVP was introduced in [4] and combines two classical combinatorial optimization … brass stitchables
