The emperor was already descended from the tower, and advancing on horse-back towards me, which had like to have cost him dear; for the beast, though very well trained, yet wholly unused to such a sight, which appeared as if a mountain moved before him, reared up on its hinder feet: but that prince, who is an excellent horseman, kept his seat.

The Graceful Tree Conjecture states that all trees have a graceful labelling. In this survey we present known results towards proving the Graceful Tree Conjecture.

Discover the world's research. Graceful Tree Conjecture (GTC) is one of my favorite open problems. I posted it on Open Problem Garden couple of years back. I enjoy reading papers related to graceful labeling and try to keep as up-to-date as possible with the progress towards GTC.

Graceful Tree Conjecture (GTC) is one of my favorite open problems. I posted it on Open Problem Garden couple of years back. I enjoy reading papers related to graceful labeling and try to keep as up-to-date as possible with the progress towards GTC.

Here is a brief introduction to GTC. An edge-graceful labelling on a simple graph without loops or multiple edges on p vertices and q edges is a labelling of the edges by distinct integers in {1,q} such that the labelling on the vertices induced by labelling a vertex with the sum of the incident edges taken modulo p assigns all values from 0 to p − 1 to the vertices.

A graph G is said to be "edge-graceful" if it admits an. little progress has been made towards resolving this conjecture. Today, some of the known graceful trees are caterpillars, trees with at most 4 endvertices, trees with diameter at most 5, and trees with at most 27 vertices.

Since the Renaissance, every century has seen the solution of more mathematical problems than the century before, yet many mathematical problems, both major and minor, still remain unsolved. These unsolved problems occur in multiple domains, including physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph, group, model.
