Two classes of shapes work, they proved: “boring parallelograms” and “surprising cyclic quadrilaterals,” cyclic meaning that all vertexes of a quadrilateral lie on a circle. FromNew York Times In the Blue Brain graph, for example, three neurons with all three synapses between them transmitt...

which satisfies two properties. First, the joint law of their top curves coincides with that of the colored height functions for the vertex model. Second, thenline ensembles satisfy an explicit Gibbs property prescribing their laws if all but a few of their curves are conditioned...

The overlay graph is much smaller than the full graph and is used to accelerate the query algorithm. The High-Performance Multilevel Routing (HPML) algorithm (Delling et al., 2009) is a variant of this approach that significantly reduces query time, but at the cost of increasing space ...
There has been an impressive series of ever-faster parameterized algorithms to solve k-Vertex Cover,Footnote 1 which led to the current-best algorithm by Chen et al. that can decide whether a graph G has a vertex cover of size k in O(1.2738k+kn) time and polynomial space [9, 10, 20...

Let 'G' = (V, E) be a graph. A subset K of V is called a vertex covering of 'G', if every edge of 'G' is incident with or covered by a vertex in 'K'. Example Take a look at the following graph − The subgraphs that can be derived from the above graph are as follows...
of the feedback vertex set, and is considered NP-hard, meaning that finding the optimal solution is computationally difficult. For directed graphs, a feedback vertex set is instead a subset of vertices whose removal results in directed acyclic graph (DAG), not necessarily a forest. This task ...
