The Lempel–Ziv–Welch (LZW) algorithm is a lossless data compression algorithm. LZW is an adaptive compression algorithm that does not assume prior knowledge of the input data distribution. This ...

Data compression is a fundamental technique in system design and communication, aiming to reduce the size of data while retaining most of the original information. This process facilitates efficient ...

Abstract: In the paper, a new parallel LZW-Like algorithm, bi-directory LZW algorithm (BD-LZW) will be interpreted. The new algorithm can be used in data compression ...

Abstract: This paper introduces an efficient data compression algorithm, which performs better then available LZW algorithm. Here, we propose a modified way to update the dictionary for LZW algorithm.

In this paper, we analyze the complexity and entropy of different methods of data compression algorithms: LZW, Huffman, Fixed-length code (FLC), and Huffman after using Fixed-length code (HFLC). We ...
