This report describes the reproducibility evaluation carried out for the research paper ''ALP: Adaptive Lossless Floating-Point Compression'', authored by Azim Afroozeh, Leonardo Kuffó, and Peter Boncz from the Centrum Wiskunde & Informatica (CWI), located in Amsterdam, Netherlands. The paper, presented at SIGMOD 2024, introduces ALP, a novel adaptive lossless compression algorithm for floating-point datasets. The results of the reproducibility evaluation confirm the core contributions of the original paper, showing that ALP consistently outperforms state-of-the-art techniques in both compression ratio and (de)compression speed.
