A Novel Efficient Graph Model for the Multiple Longest Common Subsequences (MLCS) Problem

open access: yesFrontiers in Genetics, 2017
Searching for the Multiple Longest Common Subsequences (MLCS) of multiple sequences is a classical NP-hard problem, which has been used in many applications. One of the most effective exact approaches for the MLCS problem is based on dominant point graph,

Triangles and Girth in Disk Graphs and Transmission Graphs [PDF]

open access: yes, 2019
Let S subset R^2 be a set of n sites, where each s in S has an associated radius r_s > 0. The disk graph D(S) is the undirected graph with vertex set S and an undirected edge between two sites s, t in S if and only if |st|

The most persistent soft-clique in a set of sampled graphs [PDF]

open access: yes, 2005
When searching for characteristic subpatterns in potentially noisy graph data, it appears self-evident that having multiple observations would be better than having just one.

EL-labelings and canonical spanning trees for subword complexes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We describe edge labelings of the increasing flip graph of a subword complex on a finite Coxeter group, and study applications thereof. On the one hand, we show that they provide canonical spanning trees of the facet-ridge graph of the subword complex ...

Retrieval of Injection Molding Industrial Knowledge Graph Based on Transformer and BERT

open access: yesApplied Sciences, 2023
Knowledge graphs play an important role in the field of knowledge management by providing a simple and clear way of expressing complex data relationships. Injection molding is a highly knowledge-intensive technology, and in our previous research, we have
