Abstract

The objective of this experimental study was to investigate the scalability of $gif.latex?k^n$ -trees, a compact data structure designed for representing $gif.latex?n$ -ary relations, compared to a baseline based on a plain representation of adjacency lists. A literature review of compact data structures was conducted, focusing on $gif.latex?k^n$ -trees and their potential for efficient $gif.latex?n$ -ary data representation. To assess scalability, experiments comparing $gif.latex?k^n$ -tree performance against the baseline using set intersection as a benchmark were conducted. Results demonstrated superior $gif.latex?k^n$ -tree scalability in terms of time and memory, especially for high-dimensional and clustered datasets. On average, $gif.latex?k^n$ -trees were eight times faster and consumed times less memory than the baseline. The study also analyzed the impact of the order parameter $gif.latex?k^n$ on performance, revealing a trade-off between space efficiency and query time. This study provides valuable insights into the practical applicability of $gif.latex?k^n$ -trees for managing and querying high-dimensional data.
