Graceful Labeling of Hypertrees
Graph labeling is considered as one of the most interesting areas in graph theory. A labeling for a simple graph G (numbering or valuation), is an association of non -negative integers to vertices of G (vertex labeling) or to edges of G (edge labeling) or both of them.

A graph G with m vertices and n edges, is said to be prime graceful labeling, if there is an injection from the vertices of G to {1, 2, ..., k} where k = min {2m, 2n} such that gcd ( ( ), ( )=1 and the induced injective function from the edges of G to {1, 2, ..., k − 1} defined by ( ) = | ( ) − ( ) | , the resulting edge labels are distinct. In

Graceful Labelling of Edge Amalgamation of Cycle Graph
There are various topics in graph theory. The theory of labelling is one of the topics in graph theory. The theory of labelling was introduced firstly by Alex Rosa in 1967.

Special Graceful Labelings of Irregular Fences and Lobsters
Irregular fences are subgraphs of $P_m \times P_n$ formed with $m$ copies of $P_n$ in such a way that two consecutive copies of $P_n$ are connected with one or two edges; if two edges are used, then they are located in levels separated an odd number of ...

A Translational Approach to Constraint Answer Set Solving [PDF]
We present a new approach to enhancing Answer Set Programming (ASP) with Constraint Processing techniques which allows for solving interesting Constraint Satisfaction Problems in ASP. We show how constraints on finite domains can be decomposed into logic

Odd graceful labeling on the Ilalang graph (Sn , 3) it’s variation
A graph called odd graceful graph if there is an injective mapping f:V(G) → {0,1,2,…,2q − 1} such that for each edge xy 6 E(G) labeled by |f(u) − f(v)|, and the results willform a label on the edge {1,3,5, …,2q − 1} which is bijective.

Automatically generating streamlined constraint models with ESSENCE and CONJURE [PDF]
Streamlined constraint reasoning is the addition of uninferred constraints to a constraint model to reduce the search space, while retaining at least one solution.
