  2. Code refactoring - Wikipedia

    en.wikipedia.org/wiki/Code_refactoring

    In computer programming and software design, code refactoring is the process of restructuring existing source code —changing the factoring —without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality.

  3. Coding best practices - Wikipedia

    en.wikipedia.org/wiki/Coding_best_practices

    Coding best practices or programming best practices are a set of informal, sometimes personal, rules (best practices) that many software developers, in computer programming follow to improve software quality. [1] Many computer programs require being robust and reliable for long periods of time, [2] so any rules need to facilitate both initial ...

  4. Rewrite (programming) - Wikipedia

    en.wikipedia.org/wiki/Rewrite_(programming)

    Rewrite (programming) A rewrite in computer programming is the act or result of re-implementing a large portion of existing functionality without re-use of its source code. When the rewrite uses no existing code at all, it is common to speak of a rewrite from scratch .

  5. Gödel's incompleteness theorems - Wikipedia

    en.wikipedia.org/wiki/Gödel's_incompleteness...

    Gödel's technique is to show that statements can be matched with numbers (often called the arithmetization of syntax) in such a way that "proving a statement" can be replaced with "testing whether a number has a given property". This allows a self-referential formula to be constructed in a way that avoids any infinite regress of definitions.

  6. Production (computer science) - Wikipedia

    en.wikipedia.org/wiki/Production_(computer_science)

    e. A production or production rule in computer science is a rewrite rule specifying a symbol substitution that can be recursively performed to generate new symbol sequences. A finite set of productions is the main component in the specification of a formal grammar (specifically a generative grammar ). The other components are a finite set of ...

  7. Self-modifying code - Wikipedia

    en.wikipedia.org/wiki/Self-modifying_code

    Self-modifying code. In computer science, self-modifying code (SMC or SMoC) is code that alters its own instructions while it is executing – usually to reduce the instruction path length and improve performance or simply to reduce otherwise repetitively similar code, thus simplifying maintenance. The term is usually only applied to code where ...

  8. Material implication (rule of inference) - Wikipedia

    en.wikipedia.org/wiki/Material_implication_(rule...

    Universal generalization / instantiation. Existential generalization / instantiation. In propositional logic, material implication[1][2] is a valid rule of replacement that allows a conditional statement to be replaced by a disjunction in which the antecedent is negated. The rule states that P implies Q is logically equivalent to not- or and ...

  9. Comment (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Comment_(computer_programming)

    Program code is in blue. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters. [1][2] The syntax of comments in various ...
