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

Higher-Order Associativity in Field Algebras

open access: yesMathematics, 2022
Field algebras were defined by Bakalov and Kac as an associative analogue of vertex algebras. We define the notion of higher-order associativity for field algebras and construct examples to show that higher-order associativity imposes a strictly stronger

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 ...
