ALL is the class of all decision problems.
Formally, a decision problem is a subset of the natural numbers.
Research in computability theory has typically focused on decision problems.
Thus, decision problems are equivalent to languages.
An oracle machine is an abstract machine used to study decision problems.
Formally, a decision problem is a subset of the natural numbers.
To prove subgraph isomorphism is NP-complete,it must be formulated as a decision problem.
In this sense a decision problem is equivalent to a formal language(60).
The type of computational problem: The most commonly used problems are decision problems.
A decision problem which can be solved by an algorithm is called decidable.
In computability theory,the halting problem is a decision problem which can be stated as follows.
A decision problem is a yes-or-no question on an infinite set of inputs.
In computability theory andcomputational complexity theory, a decision problem is a question in some formal system with a yes-or-no answer.
A decision problem is a problem where all the answers are YES or NO.
It has been further observed that tree automaton andlogical theories are closely connected and it allows decision problems in logic to be reduced into decision problems for automata.
A decision problem is typically represented as the set of all instances for which the answer is yes.
In computability theory and computational complexity theory,an undecidable problem is a decision problem for which it is known to be impossible to construct a single algorithm that always leads to a correct yes-or-no answer.
A decision problem X is a member of co-NP if and only if its complement X is in the complexity class NP.
Thus by providing a mathematical description of a very simple device capable of arbitrary computations, he was able to prove properties of computation in general-and in particular,the uncomputability of the Entscheidungsproblem("decision problem").
The decision problem of whether the Turing machine with index e will halt on every input is not decidable.
Equivalently, it is the class of decision problems where each"yes" instance has a polynomial size certificate, and certificates can be checked by a polynomial time deterministic Turing machine.
A decision problem is in NP if it can be solved by a non-deterministic algorithm in polynomial time.
The Mastermind satisfiability problem is a decision problem that asks,"Given a set of guesses and the number of colored and white pegs scored for each guess, is there at least one secret pattern that generates those exact scores?".
Thus, a decision problem informally phrased in terms of a formal language is also equivalent to a set of natural numbers.
The connection between these two is that if a decision problem is undecidable(in the recursion theoretical sense) then there is no consistent, effective formal system which proves for every question A in the problem either"the answer to A is yes" or"the answer to A is no".
The decision problem that asks whether a certain string s belongs to the language of a given context-sensitive grammar G, is PSPACE-complete.
There are decision problems that are NP-hard but not NP-complete, for example the halting problem. .
Contrary to decision problems that require yes or no answers, sampling problems ask for samples from probability distributions.
To show that a decision problem P is undecidable we must find a reduction from a decision problem which is already known to be undecidable to P.
If C is any decision problem, then one can define a complexity class C consisting of the languages A for which A≤ m P C{\displaystyleA\leq_{m}^{P}C}.
