Topological sorting - Wikipedia
"Dependency resolution" redirects here. For other uses, see Dependency (disambiguation). In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge (u,v) from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edge
Tree traversal - Wikipedia
Pre-order (node visited at position red ●): F, B, A, D, C, E, G, I, H;In-order (node visited at position green ●): A, B, C, D, E, F, G, H, I;Post-order (node visited at position blue ●): A, C, E, D, B, H, I, G, F. In depth-first search (DFS), the search tree is deepened as much as possible before going to the next sibling. To traverse binary trees with depth-first search, perform the following ope
List of tz database time zones - Wikipedia
The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software.[1] This is a list of time zones from release 2024a of the tz database.[2] Legend[edit] Type[edit] Canonical - The primary, preferred zone name. Link - An alternative name (alias) which links to a canonical zon
HSL and HSV - Wikipedia
Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway down each c
GPS Exchange Format - Wikipedia
GPX, or GPS Exchange Format, is an XML schema designed as a common GPS data format for software applications. It can be used to describe waypoints, tracks, and routes. It is an open format[2] and can be used without the need to pay license fees. Location data (and optionally elevation, time, and other information) is stored in tags and can be interchanged between GPS devices and software. Common s
JSON - Wikipedia
JSON (JavaScript Object Notation, pronounced /ˈdʒeɪsən/; also /ˈdʒeɪˌsɒn/) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a commonly used data format with diverse uses in electronic data interchange, including that of web applications wi

Rose (mathematics) - Wikipedia
Roses specified by the sinusoid r = cos(kθ) for various rational numbered values of the angular frequency k = n/d. Roses specified by r = sin(kθ) are rotations of these roses by one-quarter period of the sinusoid in a counter-clockwise direction about the pole (origin). For proper mathematical analysis, k must be expressed in irreducible form. In mathematics, a rose or rhodonea curve is a sinusoid
