NP-intermediate — In computational complexity, problems that are in the complexity class NP but are neither in the class P nor NP complete are called NP intermediate, and the class of such problems is called NPI. Ladner s theorem, shown in 1975 by Richard… … Wikipedia
Complexity of constraint satisfaction — The complexity of constraint satisfaction is the application of computational complexity theory on constraint satisfaction. It has mainly been studied for discriminating between tractable and intractable classes of constraint satisfaction… … Wikipedia
Constraint satisfaction problem — Constraint satisfaction problems (CSP)s are mathematical problems defined as a set of objects whose state must satisfy a number of constraints or limitations. CSPs represent the entities in a problem as a homogeneous collection of finite… … Wikipedia
