Verification
is the technical matter that relates to howaccurately the analytical ideas
are translated into computer code or mathematical formalisms. Verification aims at
assuring that a method (a.k.a. data mining technique) produces mechanically and
logically correct results. For example, debugging code is a verification process.
In terms of algorithm analysis verification is related to
algorithmic efficiency
.
Sometimes verification is referred to as an internal evaluation.
