We propose a new encoding scheme to represent binary trees with n leaves by words of length n over an alphabet with four letters. We give a characterization of these codewords.doi:10.1080/02522667.1992.10699110PalloJ.M.Taylor & Francis Group...
We find an orientation of a tree with 20 vertices such that the corresponding fixed-template constraint satisfaction problem (CSP) is NP-complete, and prov
Anevolutionary treeis a rooted tree where each internal vertex has at least two children and where the leaves are labeled with distinct symbols representing species. Evolutionary trees are useful for modeling the evolutionary history of species. Anagreement subtreeof two evolutionary trees is an evolut...

Moored by a riverbank planted with willow trees Beneath the waning moon and in the morning breeze. I'll be gone for a year. In vain would good times and fine scenes appear. However gallant I am on my part, To whom can I lay bare my heart?
// Then, create a BigText from the time string using PTerm's DefaultBigText and putils NewLettersFromString. // The Srender() function is used to save the BigText as a string. str, _ := pterm.DefaultBigText.WithLetters(putils.LettersFromString(time.Now().Format("15:04:05")))....
From here forward, we assume that T is a tree with n vertices. Given two vertices a,b∈V(T), P(a,b) will be the unique path between a and b in T. 2. Extremal ratios In this section, we consistently use the letters u,w to denote leaf vertices while v is a center vertex. Be...
Almonds with their skins on have been most successful in the past, because they’re really not that appealing with a gin and tonic. I once read somewhere that 3 to 5 almonds is a good snack when you need a quick boost. This ‘fact’ always makes Someone teases as it’s so specific...
So I smile, I pick up the stinkin’ carrot and wash it off and chop it up, maybe with just a little too much enthusiasm. Carrot juice anyone? So how have things been going with all of you? GUARDIANS OF THE FIRE PIT The fire pit up at our cabin is really, really big. The metal...
Abstract. Currently, there is a demand for software to analyze polymorphism data such as microsatellite DNA and single nucleotide polymorphism with easily
