Jul 11, 2010 · A loop invariant is a formal statement about the relationship between variables in your program which holds true just before the loop is ever run (establishing the invariant) and is true again at the bottom of the loop, each time through the loop (maintaining the invariant).

Loop invariant - Wikipedia
In computer science, a loop invariant is a property of a program loop that is true before (and after) each iteration. It is a logical assertion, sometimes checked with a code assertion. Knowing its invariant(s) is essential in understanding the effect of a loop.
In formal program verification, particularly the Floyd-Hoare approach, loop invariants are expressed by formal predicate logic and used to prove properties of loops and by extension algorithms that e…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 8 mins

Loop invariants can give you coding superpowers
A loop invariant is a statement about program variables that is true before and after each iteration of a loop. A good loop invariant should satisfy three properties: Initialization: The loop invariant must be true before the first execution of the loop.
Loop invariants - Department of Computer Science
A loop invariant is a condition that is true at the beginning and end of every loop iteration, analogously to the way that a class invariant is true at the beginning and end of every public …

initialize Q and R so that the loop invariant is true. The simplest way to do it is to set Q : = O and R:= X. The entire loop looks as follows: Q .—,— W R:=X; {hop invariant: X = Q * Y + R and …
Loop Invariant Condition - Interview Kickstart
Sep 25, 2024 · In essence, a loop invariant is a condition that is true for every iteration of the loop: before the loop starts, at the end of each iteration, at the starting of each iteration, and after the loop’s termination.
A loop invariant for a given loop is a Boolean statement that is true before the first iteration of the loop and is not changed to false during any iteration of the loop. (We call that the inductive …

We use loop invariants to help us understand why an algorithm is correct. We must show three things about a loop invariant: Initialization: It is true prior to the first iteration of the loop. …
We'll still need a rule for proving Hoare triples with loops. Here it is: p needs to be true before and after s (remember: we might need to run s again!), so it's an invariant. We'll call it the loop …
