Soud

In computer science, „sound“ refers to a property of formal systems, logics, or algorithms whereby if a statement is provable or derivable within the system, then it is also true in every model of that system. In simpler terms, if you can deduce a conclusion using the rules of the system, that conclusion must hold true across all interpretations.

The concept of soundness is often applied in the context of programming languages, type systems, and formal proofs. For example, a type system is said to be sound if any program that type-checks is guaranteed to be free of certain runtime errors related to type mismatches.

Soundness is contrasted with completeness, which is the property that if a statement is true in all models of the system, then it is also provable in the system. Together, these concepts help ensure the reliability and correctness of logical reasoning within computational frameworks.
