The circuit-finding oracle of Edmonds (1965) takes as input an independent set and an additional element, and either determines that their union is independent, or finds a circuit in the union and returns it. A rank oracle takes as its input a set of matroid elements, and returns as its output a numerical value, the rank of the given set. [9]
The DB-Engines Ranking ranks database management systems by popularity, covering over 410 systems. The ranking criteria [1] include number of search engine results when searching for the system names, Google Trends, Stack Overflow discussions, job offers with mentions of the systems, number of profiles in professional networks such as LinkedIn, mentions in social networks such as Twitter.
In language, the status of an item (usually through what is known as "downranking" or "rank-shifting") in relation to the uppermost rank in a clause; for example, in the sentence "I want to eat the cake you made today", "eat" is on the uppermost rank, but "made" is downranked as part of the nominal group "the cake you made today"; this nominal ...

A matrix that has rank min(m, n) is said to have full rank; otherwise, the matrix is rank deficient. Only a zero matrix has rank zero. f is injective (or "one-to-one") if and only if A has rank n (in this case, we say that A has full column rank). f is surjective (or "onto") if and only if A has rank m (in this case, we say that A has full row ...
Oracle cloning is the re-use of the once-constructed random oracle within the same proof (this in practice corresponds to the multiple uses of the same cryptographic hash within one algorithm for different purposes). [7] Oracle cloning with improper domain separation breaks security proofs and can lead to successful attacks. [8]
