Lambda Calculus
1930

Lambda Calculus

A formal system in mathematical logic and computer science for expressing computation based on function abstraction and application.

Generality: 500

Decidability
1931

Decidability

Whether a problem can be algorithmically solved, meaning there exists a clear procedure (algorithm) that will determine a yes-or-no answer for any given input within a finite amount of time.

Generality: 861

Turing Completeness
1936

Turing Completeness

Systems that can simulate a Turing machine's computational abilities.

Generality: 890

Church-Turing Thesis
1936

Church-Turing Thesis

A hypothesis proposing that any computational problem solvable by a human using algorithms can also be solved by a Turing machine, which forms a foundation for the theoretical limits of computation.

Generality: 500

Church Encoding
1940

Church Encoding

A technique in mathematical logic and computer science to represent data and operators in the lambda calculus.
