Präfixfreiheit
Präfixfreiheit (prefix-freeness) refers to a property in formal language theory and coding theory where a set of strings (or code words) has no element that is a prefix of another. This property is crucial in designing efficient and unambiguous coding schemes, enabling immediate and error-free decoding of concatenated code words without the need for delimiters.
A set of words is called prefix-free if, for any two distinct words in the set, none
Prefix-free codes are extensively used in data compression algorithms, such as Huffman coding, where they allow
The concept of Präfixfreiheit is also related to Kraft's inequality, which provides a criterion to determine
Overall, Präfixfreiheit is a fundamental concept in the development of lossless data compression and error detection
