👉 Unerrancy is a concept in computational complexity theory and information theory, which refers to the phenomenon where an algorithm or method is guaranteed to produce correct results with high probability. This means that if an algorithm satisfies certain conditions (e.g., it has good properties), then its execution will always result in the expected output. For example, consider the decision problem of sorting a list of n integers into two non-empty sublists such that the total sum of elements in each sublist is as close to n/
