An n-th busy beaver, BB-n or simply "busy beaver" is a Turing machine that wins the n-state busy beaver game. [4] Depending on definition, it either attains the highest score (denoted by Σ(n) [ 3 ] ) , or runs for the longest time ( S(n)) , among all other possible n -state competing Turing machines.
The beaver has been used to represent productivity, trade, tradition, masculinity, and respectability. References to the beaver's skills are reflected in everyday language. The English verb "to beaver" means working with great effort and being "as busy as a beaver"; a "beaver intellect" refers to a way of thinking that is slow and honest.
As eastern beaver populations were depleted, English, French, and American trappers pushed west. ... Busy beaver is a term in theoretical computer science which ...
Busy beaver is an English language idiom describing of a person who is particularly busy or industrious. Busy beaver and related terms may also refer to: The Busy Beaver game, in computational theory, a type of Turing machine; Busy Beavers, an online children's educational program; The Busy Beavers, a 1931 Silly Symphonies animated film
The "state" drawing of the 3-state busy beaver shows the internal sequences of events required to actually perform "the state". As noted above Turing (1937) makes it perfectly clear that this is the proper interpretation of the 5-tuples that describe the instruction. [1] For more about the atomization of Turing 5-tuples see Post–Turing machine:
"This communicates that we are busy at the moment but that we will attend to what is being discussed," says Dr. Marty Cooper, Ph.D., an associate professor at SUNY Old Westbury.
As there is a recursive formula to define it, it is much smaller than typical busy beaver numbers, the sequence of which grows faster than any computable sequence. Though too large to ever be computed in full, the sequence of digits of Graham's number can be computed explicitly via simple algorithms; the last 13 digits are ...7262464195387.
The invasive Jorō spider has baffled researchers by living near busy roads and urban places that other creatures tend to avoid. A new study might explain why.
