Descendants and ascendants in binary trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1997
There are three classical algorithms to visit all the nodes of a binary tree - preorder, inorder and postorder traversal. From this one gets a natural labelling of the n internal nodes of a binary tree by the numbers 1, 2, ..., n, indicating the sequence

TreeSwift: A massively scalable Python tree package

open access: yesSoftwareX, 2020
Phylogenetic trees are essential to evolutionary biology, and numerous methods exist that attempt to extract phylogenetic information applicable to a wide range of disciplines, such as epidemiology and metagenomics.

GPU-parallelisation of Haar wavelet-based grid resolution adaptation for fast finite volume modelling: application to shallow water flows

open access: yesJournal of Hydroinformatics, 2023
Wavelet-based grid resolution adaptation driven by the ‘multiresolution analysis’ (MRA) of the Haar wavelet (HW) allows to devise an adaptive first-order finite volume (FV1) model (HWFV1) that can readily preserve the modelling fidelity of its reference ...

In Situ Multi-Bit Decision for Successive Cancellation List Decoding of Polar Codes

open access: yesIEEE Access, 2022
Polar codes are the first capacity-achieving error-correction code which has attracted much research attention. Among many decoding methods, successive cancellation list decoding (SCLD) is considered as a representative decoding method that can achieve a

Parsing as tree traversal [PDF]

open access: yesProceedings of the 15th conference on Computational linguistics -, 1994
This paper presents a unified approach to parsing, in which top-down, bottom-up and left-corner parsers are related to preorder, postorder and inorder tree traversals. It is shown that the simplest bottom-up and left-corner parsers are left recursive and must be converted using an extended Greibach normal form.

Multi-Robot Persistent Surveillance With Connectivity Constraints

open access: yesIEEE Access, 2020
Mobile robots, especially unmanned aerial vehicles (UAVs), are of increasing interest for surveillance and disaster response scenarios. We consider the problem of multi-robot persistent surveillance with connectivity constraints where robots have to ...

On the Cutting Edge: Simplified O(n) Planarity by Edge Addition

open access: yesJournal of Graph Algorithms and Applications, 2004
We present new O(n)-time methods for planar embedding and Kuratowski subgraph isolation that were inspired by the Booth-Lueker PQ-tree implementation of the Lempel-Even-Cederbaum vertex addition method.

Efficient traversal of decision tree ensembles with FPGAs

open access: yesJournal of Parallel and Distributed Computing, 2021
System-on-Chip (SoC) based Field Programmable Gate Arrays (FPGAs) provide a hardware acceleration technology that can be rapidly deployed and tuned, thus providing a flexible solution adaptable to specific design requirements and to changing demands.In this paper, we present three SoC architecture designs for speeding-up inference tasks based on ...
