An arc in a projective plane whose secants meet some exterior line in the minimum number of points is said to be hyperfocused on that line. Such arcs are related to geometrically based secret sharing schemes. A \(k\)-arc \(\mathcal{K}\) is sharply focused on a line \(\ell\) which is external to \(\mathcal{K}\) if the \({k\choose2}\) secants of ...

In \(\text{PG}(n,q)\), a \(k\)-arc is a set of \(k\) points such that \(k\geq n+1\) but not \(n+1\) points belong to a hyperplane. A normal rational curve in \(\text{PG}(n,q)\), \(2\leq n\leq q-2\) is a \(q+1\) arc projectively equivalent to the set of points \(\{(1,t, \cdots, t^ n)\mid t\in \text{GF} (q)^ +\}\) where \(\text{GF}(q)^ +\) denotes ...

Arc-consistency and arc-consistency again [PDF]
There is no need to show the importance of arc-consistency in Constraint Networks. Mohr and Henderson [9] have proposed AC-4, an algorithm with optimal worst-case time complexity. But it has two drawbacks: its space complexity and average time complexity.

Isomorphism of graph classes related to the circular-ones property [PDF]
We give a linear-time algorithm that checks for isomorphism between two 0-1 matrices that obey the circular-ones property. This algorithm leads to linear-time isomorphism algorithms for related graph classes, including Helly circular-arc graphs, \Gamma ...

Arc‐Disjoint Cycles and Feedback Arc Sets [PDF]
AbstractIsaak posed the following problem. Suppose T is a tournament having a minimum feedback arc set, which induces an acyclic digraph with a hamiltonian path. Is it true that the maximum number of arc‐disjoint cycles in T equals the cardinality of minimum feedback arc set of T? We prove that the answer to the problem is in the negative.

Fast Arc-Annotated Subsequence Matching in Linear Space [PDF]
An arc-annotated string is a string of characters, called bases, augmented with a set of pairs, called arcs, each connecting two bases. Given arc-annotated strings $P$ and $Q$ the arc-preserving subsequence problem is to determine if $P$ can be obtained ...
