The FASTA algorithm is a heuristic method for string comparison. It was developed by Lipman and Pearson in 1985 [6] and further improved in 1988 [7]. FASTA compares a query string against a single text string. When searching the whole database for matches to a given query, we compare the query using the FASTA algorithm to every string in the database. When looking for an alignment, we might exp...

Recall that in the turnstile model, we have some high dimensional vector x ∈ Rn, and each update is of the form xi ← xi+v. We wish to support queries f(x) such as f(x) = xi or f(x) = |support(x)|. Obviously, we could store x in O(n) space or the whole stream (O(m) space), but our goal is to come up with algorithms that use much less space. We proved the following last time Claim 1. Any determin...

Phylogenetics is the area of research concerned with finding the genetic relationships between species. The basic idea is to compare specific characters (features) of the species, under the natural assumption that similar species (i.e., species with similar characters) are genetically close. The term phylogeny refers to these relationships, usually presented as a phylogenetic tree (see Figures ...
متن کاملVirtual Space as a Platform for Student Research Practices
Online learning is becoming an increasingly popular request. Many universities are moving fully or partially to this form of study. In the article, the authors considered what is virtual space, what are its criteria, as well as applicability for teaching students and passing research practices. Based on an analysis of existing virtual spaces (platforms), an experiment was conducted. The study s...
