Comparison of web browsers
A comparison of web browsers evaluates programs like Chrome, Safari, Edge, Firefox, Opera, and Brave on rendering engines, security architecture, privacy behavior, performance, and market position.
Comparison sort
A comparison sort is a sorting algorithm that orders items using only pairwise comparisons, never inspecting key structure. Quicksort, merge sort, and Timsort are examples.
Compass
Compass FM is a non-profit community radio station in North Canterbury, New Zealand, launched in 2011. It transmits from Mt Grey with repeaters covering Kaikoura to Ashburton.
Compass gait
The compass gait is a minimal mathematical model of bipedal walking with two rigid legs hinged at the hip, walking passively down a slope under gravity.
COMPASS-U
COMPASS-U (COMPASS Upgrade) is a medium-size, high-magnetic-field tokamak under construction at the Institute of Plasma Physics in Prague, replacing COMPASS in 2021 to support ITER and address DEMO design challenges.
CompassKit
CompassKit is the collection of evaluation toolkits for large language models and large vision-language models that forms one of three components of OpenCompass 2.0, released by Shanghai AI Laboratory in January 2024 alongside CompassHub and CompassRank.
Compatibilizer
A compatibilizer is a polymer additive, usually a block or graft copolymer, that improves immiscible polymer blends by lowering interfacial tension and strengthening adhesion between phases.
CompCert
CompCert is a formally verified optimizing compiler for a large subset of the C language, developed since 2005 by Xavier Leroy and collaborators, with machine-checked proof ruling out miscompilation.
Compensation grouting
Compensation grouting is a geotechnical technique that injects cement grout between a tunnel and the structures above it to offset tunnelling settlement, first used in the UK at Waterloo Station and later beneath Big Ben.
Competition between Airbus and Boeing
The competition between Airbus and Boeing is the duopoly rivalry in large commercial aircraft, with Airbus leading recent deliveries and a record backlog of 8,754 jets in 2025.
Competitions and prizes in artificial intelligence
Competitions and prizes in artificial intelligence are organized contests, from Kaggle data-science challenges to DARPA grand challenges, that advance the state of the art and recruit talent.
Competitive analysis (online algorithms)
Competitive analysis is a method for evaluating online algorithms that make decisions without knowing future requests, comparing their cost to an optimal offline algorithm on every input.
Competitive Power Ventures
Competitive Power Ventures (CPV) is an American independent power company headquartered in Silver Spring, Maryland. Founded in 1999, it develops natural gas, wind, and solar generation projects.
Competitive programming
Competitive programming, also known as competitive coding, is a mind sport in which contestants write programs solving precisely specified algorithmic problems within strict time and memory limits, verified by automated judges.
Compiler
A compiler is a program that translates source code into machine code or an intermediate form before execution, unlike interpreters; Grace Hopper completed the first compiler, A-0, in 1952.
Compiler optimization
Compiler optimization is the set of techniques a compiler applies to make programs faster, smaller, or more energy-efficient while preserving behavior, structured as passes over intermediate code.
Complementary filter
A complementary filter is a sensor-fusion algorithm that blends a drifting gyroscope with a noisy accelerometer, best known for attitude estimation on UAVs and self-balancing robots.
Completely Fair Scheduler
The Completely Fair Scheduler, or CFS scheduler, is a Linux kernel process scheduler by Ingo Molnar that gave each task a fair share of CPU time.
