Encyclopedia > Invariant (computer science)

In computer science, optimising compilers and the methodology of design by contract pay close attention to invariant quantities in computer programs, where the set of transformations involved is the execution of the steps of the computer program.


A loop invariant is a constraint on the input to a loop that should be satisfied by every iteration of the loop.


A class invariant is a constraint on the state of an object that should be satisfied by every method of the class.

In its most general sense, computer science (CS or compsci) is the study of computation and information processing, both in hardware and in software.
In practice, computer science includes a variety of topics relating to computers, which range from the abstract analysis of algorithms, formal grammars, etc. to more concrete subjects like programming languages, software, and computer hardware.
Science kits, science lessons, science toys, maths toys, hobby kits, science games and books - these are some of many products that can help give your kid an edge in their science fair projects, and develop a tremendous interest in the study of science.
