Evaluation of teaching quality based on binary tree support vector machine [PDF]

open access: yesMATEC Web of Conferences, 2022
In order to solve the reliability of the evaluation results of teaching quality in universities and colleges, an improved model of teaching evaluation based on the Support vector machine was put forward. In this model, the evaluator does not need to give

Non-binary universal tree-based networks

open access: yesJournal of Graph Algorithms and Applications, 2022
A tree-based network $N$ on $X$ is called universal if every phylogenetic tree on $X$ is a base tree for $N$. Recently, binary universal tree-based networks have attracted great attention in the literature and their existence has been analyzed in various

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

A combinatorial method to find sharp lower bounds on flip distances [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Consider the triangulations of a convex polygon with $n$ vertices. In 1988, Daniel Sleator, Robert Tarjan, and William Thurston have shown that the flip distance of two such triangulations is at most $2n-10$ when $n$ is greater than 12 and that this ...

Embedding phylogenetic trees in networks of low treewidth [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Given a rooted, binary phylogenetic network and a rooted, binary phylogenetic tree, can the tree be embedded into the network? This problem, called \textsc{Tree Containment}, arises when validating networks constructed by phylogenetic inference methods ...

Non-Binary Tree Reconciliation with Endosymbiotic Gene Transfer [PDF]

open access: yes, 2022
Gene transfer between the mitochondrial and nuclear genome of the same species, called endosymbiotic gene transfer (EGT), is a mechanism which has largely shaped gene contents in eukaryotes since a unique ancestral endosymbiotic event know to be at the ...

Implicit inequality constraints in a binary tree model [PDF]

open access: yes, 2011
In this paper we investigate the geometry of a discrete Bayesian network whose graph is a tree all of whose variables are binary and the only observed variables are those labeling its leaves.
