Theory exploration of binary trees [PDF]

open access: yes2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY), 2015
The construction of a theory for binary trees is presented, based on the systematic exploration of the properties necessary for the proof-based synthesis and certification of sorting algorithms for binary trees. The process is computer supported, being realised in the frame of the Theorema system, with some additional proofs in Coq required for ...

Snake Graphs Arising from Groves with an Application in Coding Theory

open access: yesComputation, 2022
Snake graphs are connected planar graphs consisting of a finite sequence of adjacent tiles (squares) T1,T2,…,Tn. In this case, for 1≤j≤n−1, two consecutive tiles Tj and Tj+1 share exactly one edge, either the edge at the east (west) of Tj (Tj+1) or the ...

Classifying Conserved RNA Secondary Structures With Pseudoknots by Vector-Edit Distance

open access: yesIEEE Access, 2021
Secondary structures have been proved to relate with the great functional diversity of RNA. There have been many studies to predict and compare the RNA secondary structures. However, fast and accurate comparison of RNA secondary structures with arbitrary

On the maximum number of period annuli for second order conservative equations

open access: yesMathematical Modelling and Analysis, 2021
We consider a second order scalar conservative differential equation whose potential function is a Morse function with a finite number of critical points and is unbounded at infinity.
