Abstract. We present a new algorithm that can output the rankdecomposition of width at most k of a graph if such exists. For that we use an algorithm that, for an input matroid rep...
Abstract. We give an fpt approximation algorithm for the directed vertex disjoint cycle problem. Given a directed graph G with n vertices and a positive integer k, the algorithm co...
The migration of lymphocytes through secondary lymphoid organs was believed to be mainly controlled by chemokine gradients. This theory has recently been called into question since...
In computability theory, program self-reference is formalized by the not-necessarily-constructive form of Kleene’s Recursion Theorem (krt). In a programming system in which krt h...
Visual notations are pervasive in circuit design, control systems, and increasingly in mainstream programming environments. Yet many of the foundational advances in programming la...
