In computational complexity theory, a branch of computer science, Schaefer's theorem states necessary and sufficient conditions under which a finite set S of Boolean relations yields polynomial-time or NP-complete problems when the relations of S are used to constrain some of the propositional variables. More precisely, Schaefer defines a decision problem which he calls the Generalized Satisfiability problem for S (denoted SAT(S)). The problem is to determine whether the given formula is satisfiable, in other words if the variables can be assigned values such that they satisfy all the constraints. Special cases of SAT(S) include the variants of Boolean satisfiability problem and the problem can also be viewed as a constraint satisfaction problem over the Boolean domain.…

In computational complexity theory, the complexity class NP-complete (abbreviated NP-C or NPC), is a class of problems having two properties: Any given solution to the problem can be verified quickly (in polynomial time); the set of problems with this property is called NP (nondeterministic polynomial time). If the problem can be solved quickly (in polynomial time), then so can every problem in NP. Although any given solution to such a problem can be verified quickly, there is no known efficient way to locate a solution in the first place; indeed, the most notable characteristic of NP-complete problems is that no fast solution to them is known. That is, the time required to solve the problem using any currently known algorithm increases very quickly as the size of the problem grows. As a result, the time required to solve even moderately large versions of many of these problems easily reaches into the billions or trillions of years, using any amount of computing power available today. As a consequence, determining whether or not it is possible to solve these problems quickly is one of the principal unsolved problems in computer science today.…

Set packing is a classical NP-complete problem in computational complexity theory and combinatorics, and was one of Karp's 21 NP-complete problems. Suppose we have a finite set S and a list of subsets of S. Then, the set packing problem asks if some k subsets in the list are pairwise disjoint (in other words, no two of them intersect). The problem is clearly in NP since, given k subsets, we can easily verify that they are pairwise disjoint. The optimization version of the problem, maximum set packing, asks for the maximum number of pairwise disjoint sets in the list. It is a maximization problem that can be formulated naturally as an integer linear program, belongs to the class of packing problems, and its dual linear program is the set cover problem.…

ASR-complete is, by analogy to NP-completeness in complexity theory, a term to indicate that the difficulty of a computational problem is equivalent to solving the central Automatic Speech Recognition problem, i.e. recognize and understanding spoken language. Note that unlike NP-completeness, this term is typically used more informally.These problems are easy for humans to do (in fact, they are described directly in terms of imitating humans). Some systems can solve very simple restricted versions of these problems, but none can solve them in their full generality.…

In the mathematical discipline of graph theory, a vertex cover of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. The problem of finding a minimum vertex cover is a classical optimization problem in computer science and is a typical example of an NP-hard optimization problem that has an approximation algorithm. Its decision version, the vertex cover problem was one of Karp's 21 NP-complete problems and is therefore a classical NP-complete problem in computational complexity theory. Furthermore, the vertex cover problem is fixed-parameter tractable and a central problem in parameterized complexity theory. The minimum vertex cover problem can be formulated as a half-integral linear program whose dual linear program is the maximum matching problem.…

The complexity ofconstraint satisfaction is the application of computational complexitytheory on constraint satisfaction. It has mainly been studied fordiscriminating between tractable and intractable classes of constraintsatisfaction problems on finite domains. Solving a constraintsatisfaction problem on a finite domain is an NP-complete problem ingeneral. Research has shown a number of polynomial-time subcases, mostlyobtained by restricting either the allowed domains or constraints or theway constraints can be placed over the variables. Research has alsoestablished relationship of the constraint satisfaction problem withproblems in other areas such as finite model theory and databases.…

In computationalcomplexity theory, the Maximum Satisfiability problem, or MAX-SAT, isthe problem of determining the maximum number of clauses, of a givenBoolean formula, that can be satisfied by some assignment. The MAX-SATproblem is NP-hard, since its solution easily leads to the solution ofthe boolean satisfiability problem, which is NP-complete. It is alsoAPX-complete, and thus does not admit a PTAS unless P = NP. MAX-SAT isone of the optimization extensions of the boolean satisfiabilityproblem, which is the problem of determining if the variables of a givenBoolean formula can be assigned in such a way as to make the formulaevaluate to TRUE. If the clauses are restricted to have at most 2literals, as in 2-satisfiability, we get the MAX-2SAT problem. If theyare restricted to at most 3 literals per clause, as in 3-satisfiabilitywe get the MAX-3SAT problem.…

In computational complexity theory, a numeric algorithm runs in pseudo-polynomial time if its running time is polynomial in the numeric value of the input (which is exponential in the length of the input - its number of digits). An NP-complete problem with known pseudo-polynomial time algorithms is called weakly NP-complete. An NP-complete problem is called strongly NP-complete if it is proven that it cannot be solved by a pseudo-polynomial time algorithm unless P=NP. The strong/weak kinds of NP-hardness are defined analogously. Consider the problem of testing whether a number n is prime, by naively checking whether no number in {2,3., n/2} divides n evenly. This approach can take up to n/2-1 divisions, which is indeed linear in n but not in the size of n. For example, the number n = 2,000,000,000 would require approximately 1 billion divisions, even though the length of n is only 10 digits.…

In complexitytheory, maximum common subgraph- isomorphism (MCS) is an optimizationproblem that is known to be NP-hard. The associated decision problemi.e., given G1, G2 and an integer k, deciding whether G1 contains asubgraph of at least k edges isomorphic to a subgraph of G2 isNP-complete. One possible solution for this problem is to build amodular product graph, in which the largest clique represents a solutionfor the MCS problem. MCS algorithms have a long tradition incheminformatics and pharmacophore mapping.…

In the field ofartificial intelligence, the most difficult problems are informallyknown as AI-complete or AI-hard, implying that the difficulty of thesecomputational problems is equivalent to solving the central artificialintelligence problem-making computers as intelligent as people, orstrong AI. The term was coined by Fanya Montalvo by analogy withNP-complete and NP-hard in complexity theory, which formally describesthe most famous class of difficult problems. Early uses of the term arein Erik Mueller's 1987 Ph.D. dissertation and in Eric Raymond's 1991Jargon File.…
