UnverifiedLZ77 uses a sliding window to find repeated byte strings and represents repetitions as (distance, length) pairs; LZ78 builds a dictionary and encodes repeated strings as indices. Both achieve lossless compression.70% similarUnverifiedLempel-Ziv Plurality (LZP) is an algorithm proposed by Kosoy that uses the Lempel-Ziv decomposition of a string to predict the next symbol.68% similarUnverifiedFor a string of length n with z LZ77 phrases, LZP makes at most O(z log n) errors.60% similarUnverifiedLZ4's matching strategy: it keeps only hash table indexes for the most recent bytes, and match lookup performs just one probe with no backtracking.57% similarUnverifiedZGCM-1-7B remains competitive with large models such as Qwen3-235B-A22B and GLM-5.1 on mathematical reasoning and agentic search tasks.57% similar
