Fast Quasi-Threshold Editing
[article]
2015
arXiv
pre-print
Given a graph it computes a quasi-threshold graph which is close in terms of edit count. This edit problem is NP-hard. ...
We introduce Quasi-Threshold Mover (QTM), an algorithm to solve the quasi-threshold (also called trivially perfect) graph editing problem with edge insertion and deletion. ...
We generated graphs by applying random edits to quasi-threshold graphs. ...

We introduce Quasi-Threshold Mover (QTM), an algorithm to solve the quasi-threshold (also called trivially perfect) graph editing problem with a minimum number of edge insertions and deletions. ...
Given a graph it computes a quasi-threshold graph which is close in terms of edit count, but not necessarily closest as this edit problem is NP-hard. ...
In this paper we fill this gap by introducing Quasi-Threshold Mover (QTM), the first scalable quasi-threshold editing heurist ic. ...

Additionally, we show that for almost all graphs, solutions of the previously proposed quasi-threshold editing heuristic QTM are close to optimal. ...
We study the {C_4, P_4}-free editing problem, which is the problem of finding a minimum number of edge insertions or deletions to transform an input graph into a quasi-threshold graph. ...
These are also called quasi-threshold or trivially perfect graphs. Quasi-threshold editing has applications in detecting communities in social friendship networks. ...

This algorithm attempts to bridge the gap between fast "mapping" algorithms and more traditional alignment procedures. ...
We remove all alignments with edit distance greater than a userprovided threshold. ...

Fast discovery and visualization of conserved regions in DNA sequences using quasi-alignment
2013
BMC Bioinformatics
The method is based on approximating edit distance between segments of sequences using p-mer frequency counts. ...
Since the run time is linear and the sequences are converted into a compact clustering model, we are able to identify conserved regions fast or even interactively using a standard PC. ...
For creating GenModels, the default is Manhattan distance with a clustering threshold distance of 30 which requires a minimum edit distance of 5 between two segments to place the into separate clusters ...

Possible effects of the break-up channel on the elastic scattering threshold anomaly has been investigated. ...
When one of the participants is weakly bound, there is a possibility of having a break-up channel that does not close so fast in the vicinity of the Coulomb barrier. ...

Temperature Anisotropy in a Shocked Plasma: Mirror-Mode Instabilities in the Heliosheath
2007
Astrophysical Journal
Shocked plasma with enhanced plasma beta is preferentially unstable to the mirror mode instability downstream of a quasi-perpendicular shock and to the firehose instability downstream of a quasi-parallel ...
The fire-hose instability arises from the fast MHD mode and produces large-amplitude transverse waves. ...
