realiserbara

Realiserbara is a Swedish adjective that translates roughly to realizable or feasible in English. It is used to describe things that can be brought into existence, achieved, or carried out within given constraints such as time, resources, or laws. The form is built from the root realiser- (to realize) plus the suffix -bar, which signals capability or possibility.

In formal contexts, realiserbara often appears in discussions about feasibility studies, project planning, and engineering where tasks, designs, or outcomes are evaluated for realizability. In logic and computer science, the related concept of realizability provides a framework to connect propositions with constructive witnesses or computational entities, indicating that a statement has a concrete realization or algorithmic content.

Realizability as a technical method originated with Kleene’s realizability interpretation of intuitionistic logic in the 1950s. Since then, several variants have been developed, including modified realizability and Krivine’s realizability, each aiming to extract computational meaning from proofs and to connect logical truth with executable procedures. While these ideas are primarily explored in English-language literature, the Swedish term realiserbara is used in translated or localized discussions to express the same notion of constructive realizability.

Applications of realizability concepts include program extraction from proofs, formal verification, constructive mathematics, and type theory. They provide a bridge between abstract logical statements and concrete algorithms, enabling the development of verified software and rigorous computational interpretations of mathematical theories.
