Fastest algorithm to construct a proper edge $(\Delta(G)+1)$-coloring of a simple graph
A proper edge coloring is a coloring of the edges of a graph so that adjacent edges receive distinct colors. Vizing's theorem states that every simple graph $G$ has a proper edge coloring using at mos …

What is the optimal upper bound of $|T_1|+|T_2|+|T_3|$ if $T_1, T_2, T_3$ are trees covering...
By a classical theorem of Nash-Williams, the edges of every connected $n$-vertex planar graph can be covered by three trees $T_1,T_2$ and $T_3$. Does anyone know of any results from an article or a te …
