Extremal Combinatorics
Hamming distance is a metric used to measure the difference between two strings of equal length, calculated as the number of positions at which the corresponding symbols differ. This concept is fundamental in various applications, including error detection and correction in coding theory, where it helps identify how many errors have occurred during data transmission. Additionally, Hamming distance plays a crucial role in optimizing network designs and in tackling extremal problems in hypergraphs by analyzing how different structures can be distinguished based on their distance from one another.
