# Correctness (computer science) ## MicroSim spec - **Recommended sim type:** verification / coverage - **Microsimmability score:** 80/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Input space coverage` - `Bug density` - `Test cases` ### What animates Test cases sweep an input space; the probability of an undetected fault falls as coverage rises against a fixed bug [[Density|density]]. ### Learning objective Relate confidence in correctness to coverage and defect density. ## Links (Wikipedia order) <!-- injected from _registry/childlinks/Correctness_(computer_science).json (2026-07-30T02:09:12Z) --> [[Accuracy_and_precision]] · `Acta_Informatica` · [[Adaptability]] · [[Algorithm]] · [[Algorithmic_efficiency]] · `C_(programming_language)` · `Communications_of_the_ACM` · `Compiler_correctness` · `Computer_memory` · [[Computer_programming]] · `Constructive_logic` · `Curry–Howard_correspondence` · `Design_by_contract` · [[Flexibility_(engineering)]] · [[Formal_system]] · `Formal_verification` · `Halting_problem` · `Hoare_logic` · `ISO/IEC_9126` · `Integer` · `Lambda_calculus` · `List_of_system_quality_attributes` · [[Loose_coupling]] · [[Maintainability]] · `Mathematical_proof` · `Model_checking` · [[Non-functional_requirement]] · `Number_theory` · [[Orthogonality_(programming)]] · `Perfect_number` · `Program_analysis` · `Program_derivation` · `Proof_theory` · [[Reliability_engineering]] · [[Reusability]] · [[Robustness_(computer_science)]] · [[Scalability]] · [[Software_portability]] · [[Software_quality]] · [[Software_quality_assurance]] · [[Software_quality_control]] · [[Software_quality_management]] · [[Software_sizing]] · [[Software_testability]] · `Software_testing` · `Theoretical_computer_science` · `Tony_Hoare` · `Undecidable_problem` · [[Usability]] · `Victor_Basili` > p5.js MicroSim stub · part of System Quality Attributes · [Wikipedia source](https://en.wikipedia.org/wiki/Correctness_%28computer_science%29) > Relation: subfield of system quality attributes. ## Concept summary Correctness is the property that a program satisfies its specification on all valid inputs. ## Build checklist - [ ] Claim it: set `status: in-progress` + `lease` + `leased_at` - [ ] Write the child page explaining the concept (tie it back to system quality attributes) - [ ] Finalize parameter ranges and defaults - [ ] Implement the p5.js sketch (drawing + control regions) - [ ] Add caption + the learning objective on the page - [ ] Set `status: done` ## p5.js sketch ```javascript // MicroSim: Correctness (computer science) let controls = {}; function setup() { // createCanvas(...); create sliders for the parameters above. } function draw() { // background(...); read controls; render verification / coverage; respond live. } ``` --- Back to System Quality Attributes · Wikipedia: [Correctness (computer science)](https://en.wikipedia.org/wiki/Correctness_%28computer_science%29) --- <!-- SEMIOTIC-PROFILE:START --> ## Semiotic profile > *The semiotic universals this article invokes, machine-derived from the crossref — **unverified** (born so).

Best explored is functional correctness, which refers to the input-output behavior of the algorithm: for each input it produces an output satisfying the specification.[1] ([Wikipedia](https://en.wikipedia.org/wiki/Correctness_%28computer_science%29)) <!-- REAL-GENERATIVE-MEDIA:END --> ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Correctness_%28computer_science%29) : [Wikitube](https://en.wikitube.io/wiki/Correctness_%28computer_science%29) ## Previous hub tags Tree parent: [[Reliability_engineering]].
