= Re-Pair
{wiki=Re-Pair}
Re-Pair is a data compression algorithm that is particularly effective for compressing strings. It is a variant of the pair grammar-based compression methods, which work by identifying and replacing frequent pairs of symbols in a dataset. The core idea of Re-Pair is to analyze the input string and iteratively replace the most frequent pair of adjacent symbols (or characters) with a new symbol that does not appear in the original data, thus reducing the overall size of the string.
