WebTools. In theoretical physics, an invariant is an observable of a physical system which remains unchanged under some transformation. Invariance, as a broader term, also applies to the no change of form of physical laws under a transformation, and is closer in scope to the mathematical definition. Invariants of a system are deeply tied to the ... WebA 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 ).
