Counting hash collisions with the birthday paradox

Read Original

This technical article explores the connection between the birthday paradox and hash function collisions. It provides a detailed mathematical derivation for calculating the expected number of collisions in a set of values when using a uniform hash function with a given range. The author explains the formula and its nuances, clarifying what it counts (e.g., sequential matches) and its practical applications, such as in patient-matching networks.
