Algonquin Round Table
The Algonquin Round Table, or Vicious Circle, was a New York literary luncheon group of writers, critics, actors, and press agents, including Dorothy Parker, Robert Benchley, and Harold Ross, that met daily at the Algonquin Hotel from June 1919 into the late 1920s, famous for the wit disseminated through Franklin P. Adams's column The Conning Tower and the 1922 revue No Sirree!.
Algor mortis
Algor mortis is the postmortem cooling of a body after death, used with the Henssge nomogram to estimate the postmortem interval, typically within the first 24-80 hours, limited by ambient temperature, body mass, clothing, and refrigeration.
Algorithm
An algorithm is a finite, clearly specified set of rules or steps for carrying out a computation that produces a prescribed result for any input in a class of inputs.
Algorithm (Natalie Imbruglia album)
Algorithm is Natalie Imbruglia's seventh studio album, released September 4, 2026 on her independent label Landgirl Records; a 12-track, 36-minute synth-pop and dance record about social media, perimenopause, and mental health.
Algorithmic Accountability Act
The Algorithmic Accountability Act is a recurring US congressional bill, first introduced by Senator Ron Wyden in 2019, that would direct the FTC to require impact assessments of automated decision systems.
Algorithmic bias
Algorithmic bias, also called machine learning bias, is a systematic error in a computational decision system that disadvantages unprivileged groups, often without discriminatory intent, as in the 2016 COMPAS case.
Algorithmic Combinatorics on Partial Words

Algorithmic probability
Algorithmic probability, also called Solomonoff or universal probability, is a mathematical prior introduced by Ray Solomonoff in 1960 that assigns shorter strings higher probability and underlies Solomonoff induction.
Algorithmic self-assembly of DNA
Algorithmic self-assembly of DNA is a molecular programming technique, founded on Erik Winfree's 1998 Caltech thesis, in which DNA tiles with designed binding rules grow into crystals that compute.
Algorithmic stability
Algorithmic stability is a machine learning property where a learning algorithm's output and loss change little when one training example is changed, providing generalization bounds independent of hypothesis space complexity.
Algorithmic trading
Algorithmic trading, also known as algo trading or robo-trading, is the use of computer algorithms that automatically determine order parameters like timing, price, and quantity, including high-frequency trading.
Algorithms for calculating variance
Algorithms for calculating variance are the numerical procedures used to compute variance, whose naive one-pass formula loses precision while Welford's and pairwise methods stay stable.
Algorithms on special graph classes
Algorithms on special graph classes solve hard graph problems efficiently by exploiting structural restrictions such as chordal, perfect, or bounded-treewidth graphs, turning NP-complete tasks into linear-time ones.
Algospeak
Algospeak, also known as Unalived, is a 21st-century linguistic phenomenon that uses coded language and modified spellings across social media platforms to evade automated content moderation.
Algospeak (book)
Algospeak (Algospeak: How Social Media Is Transforming the Future of Language) is Adam Aleksic's 2025 Knopf book arguing that social media algorithms drive language change, with 'unalive' and 'seggs' as examples.
