What is the meaning of computable?
capable of being computed
Definition of computable : capable of being computed.
What is computable problem?
A mathematical problem is computable if it can be solved in principle by a computing device. Some common synonyms for “computable” are “solvable”, “decidable”, and “recursive”. Hilbert believed that all mathematical problems were solvable, but in the 1930’s Gödel, Turing, and Church showed that this is not the case.
What is a computable program?
A function f: Σ* Σ* is computable if there is a. program P that when executed on an ideal computer (one with infinite memory), computes f. That is, for all strings x in Σ*, f(x) = P(x).
What does not computable mean?
(Undecidable simply means non-computable in the context of a decision problem, whose answer (or output) is either “true” or “false”). Non-Computable Problems – A non-computable is a problem for which there is no algorithm that can be used to solve it.
What makes a function computable?
Computable functions are the formalized analogue of the intuitive notion of algorithms, in the sense that a function is computable if there exists an algorithm that can do the job of the function, i.e. given an input of the function domain it can return the corresponding output.
What is computable function how is it useful and used?
What does it mean to be effectively computable?
is effectively computable if there is an effective procedure or algorithm that correctly calculates f. An effective procedure is one that meets the following specifications.
Is Computably a word?
Computably definition In a computable manner. With regard to computability.
Are all numbers computable?
Real numbers used in any explicit way in traditional mathematics are always computable in this sense. But as Turing pointed out, the overwhelming majority of all possible real numbers are not computable. For certainly there can be no more computable real numbers than there are possible Turing machines.
Is every function computable?
I’d like to share a simple proof I’ve discovered recently of a surprising fact: there is a universal algorithm, capable of computing any given function!
What is computable function in AI?
How do you show that a function is computable?
Now, consider g(p). As ϕp(x)↓ for all x≥1, g(p)=1 if and only if ϕp(p)↓ by the definition of ϕp, which is actually the function g. Hence, if g would be computable, the halting problem would be computable as well. Therefore, we reach a contradiction.
What problem is not computable?
Non-Computable Problems – A non-computable is a problem for which there is no algorithm that can be used to solve it. Most famous example of a non-computability (or undecidability) is the Halting Problem.

What does it mean for a problem to be undecidable?
(definition) Definition: A problem that cannot be solved for all cases by any algorithm whatsoever—equivalently, whose associated language cannot be recognized by a Turing machine that halts for all inputs. Specialization (… is a kind of me.) halting problem, Post’s correspondence problem.
What makes a number computable?
A real number is computable if and only if the set of natural numbers it represents (when written in binary and viewed as a characteristic function) is computable.
How do you throttle someone?
To throttle someone means to kill or injure them by squeezing their throat or tightening something around it and preventing them from breathing. The attacker then tried to throttle her with wire.
Is Tumpine a word?
Captain, Good, Graceful.
How do you show a problem is undecidable?
If CONST = TOTALP, then TOTALP outputs Yes for all inputs, which implies that P(x) halts on all inputs, which implies that P(x) is total. Thus, if we can determine whether CONST = TOTALP, we can solve the totality problem. Therefore, the equivalence problem is undecidable.
What does it mean to compute something?
To use a computer. 3. To be reasonable, plausible, or consistent; make sense: Your alibi doesn’t compute. n. Computation: amounts beyond compute. [French computer, from Old French, from Latin computāre : com-, com- + putāre, to reckon; see pau- in Indo-European roots.
What is the capability of being compute?
Capable of being computed. (computing theory) algorithmically computable, i.e. able to be calculated by a Turing machine.
What is another word for calculable?
computable – may be computed or estimated; “a calculable risk”; “computable odds”; “estimable assets”. estimable. calculable – capable of being calculated or estimated; “a calculable risk”; “calculable odds”.
Why are some computations inherently difficult?
There are computations that are inherently difficult to such an extent that even though we are logically allowed to know the result actually finding it is well beyond any reasonable resource allocation. What makes one problem difficult an another easy is an interesting study in its own right and this is where we start.
