“Cuckoo hashing addresses the problem of implementing an open addressing hash table with worst case constant lookup time. Specifically, a constant number of entries in the hash table should be associated with each key x, such that x is present in one of these entries if x ∊ S.” [1, 2, 3]
Theorem 1.1. Any instance carrying merely characteristics above (e.g. Cuckoo Hashing) lacks creativity.
To make it clear, let's consider two parts of the citation above:
PART ONE: “…with worst case constant lookup time.…”¹ is great discovery, but the point is when it comes to consider Intellectual Issues, even the most powerful method in Information Technology (IT) is useless, because for example hashing functions return an index merely for a given word/terminology (= input), while we don't have any in such situations; it's creation important.
PART TWO: “...Specifically, a constant number of entries in the hash table should be associated with each key x...” means creeping accumulation in clusters, while creativity is quite against it; no walls and no boundary!
This last verse is even achievable with Second Rule of the ConceptBase, which says:
Second Rule: To a huge extend a concept could be recognized, by a Man, and/or Machine by having known the two opposite side of the concept, and everything in betwixt and between (implicitly/explicitly), with gradually ascending or descending, e.g. baking, broil, ..., muggy, snug, cosy, ..., equilibrium, ..., frigid, monkey weather, brass monkeys, ..., frosty, freezing, Arctic, perishing; with several parameters and offsets defined. so the ConceptBase with this rule holds tons of stuff which finds them in a heartbeat. http://neugenery.blog.com/conceptbase-vs-database/
¹ O(1), but the results are out on a limb, i.e.: http://neugenery.blog.com/spiking-pattern/
