Data types | Abstract data types
In computer science, the augmented map is an abstract data type (ADT) based on ordered maps, which associates each ordered map an augmented value. For an ordered map with key type , comparison function on and value type , the augmented value is defined based on two functions: a base function and a combine function , where is the type of the augmented value. The base function converts a single entry in to an augmented value, and the combine function combines multiple augmented values. The combine function is required to be associative and have an identity (i.e., forms a monoid). We extend the definition of the associative function as follows: Then the augmented value of an ordered map is defined as follows: Accordingly, an augmented map can be formally defined as a seven-tuple . For example, an augmented map with integral keys and values, on which the augmented value is defined as the sum of all values in the map, is defined as: As an abstract data type, the augmented map is often used to model problems and serves as an abstraction with a useful interface. It is designed for supporting fast range sums, which means to quickly return the augmented value of all entries in a certain key range. (Wikipedia).
Modeling a 2-Piece Candle Holder in GeoGebra Augmented Reality
Math Teachers: Students can use GeoGebra Augmented Reality to create surfaces formed by rotating the graph of a function y = f(x) about the x-axis! Here's how: https://www.geogebra.org/m/RKYFdQJy#material/kPNmmHgj.
