    algorithm (countable anduncountable,pluralalgorithms)

    1. (countable) A collection of ordered steps that solve a mathematical problem. A precise step-by-step plan for a computational procedure that possibly begins with an input value and yields an output value in a finite number of steps.
      • 1990, Cormen, Leiserson, and Rivest,Introduction to Algorithms: page 1. Cambridge, MA, The MIT Press, 1999 (23rd printing)
        Informally, analgorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. Analgorithm is thus a sequence of computational steps that transform the input into the output.
      • 2010,Aaron Sorkin,The Social Network:
        Mark Zuckerberg: No, I need thealgorithm you used to rank chess players. / Eduardo Saverin: Are you OK? / Mark Zuckerberg: We're ranking girls.
      • 2013 July 26,Leo Hickman, “How algorithms rule the world”, inThe Guardian Weekly‎[1], volume189, number 7, page26:
        The use ofalgorithms in policing is one example of their increasing influence on our lives. And, as their ubiquity spreads, so too does the debate around whether we should allow ourselves to become so reliant on them – and who, if anyone, is policing their use.
      • 2018 June 25, Sam Jones, “Ex-Nato chief refused visa waiver to US because of Iran trips”, inThe Guardian:
        It’s a computer – analgorithm – and if you’ve been in Iran lately, they take you out of the system.
    2. (loosely) Aflowchart illustrating adecision-making process for human users, especially health care professionals.
      • 2023, Lee SG, Blood AJ, Cannon CP, Gordon WJ, Nichols H, Zelle D, Scirica BM, Fisher NDL, “Remote cardiovascular hypertension program enhanced blood pressure control during the COVID-19 pandemic”, inJ Am Heart Assoc, volume12, number 6,→DOI,→PMID, pagee027296:
        This retrospective observational analysis evaluated BP [blood pressure] control in an entirely remote management program before and during the pandemic. A team of pharmacists, nurse practitioners, physicians, and nonlicensed navigators used an evidence‐based clinicalalgorithm to optimize hypertensive treatment. Thealgorithm was adapted during the pandemic to simplify BP control.
    3. (uncountable,obsolete)Calculation withArabic numerals;algorism.
    4. (social media,metonymic)recommender systems and thecuration offeeds
      1. (usually proceeded bydefinite article "the") software that makes content display determinations on a platform, in totality of effect upon allend users (within a potential audience).
      2. (informal, by extension of above) the influencedzeitgeist: e.g. what content ends uptrending orviral, what persons become amain character orcancelled
        • 2018 February 26, Tad Friend, quotingDonald Glover, “Donald Glover Can’t Save You”, inThe New Yorker‎[2]:
          Glover began his acceptance speech by saying, “First, I want to thank the greatalgorithm that put us all here.”

          … you and I probably didn't run across that inour algorithm, but that doesn't mean that a lot of people aren't gonna run across garbage like that intheir algorithms in the next couple weeks…
