GCMF: A Reference Implementation of General-Purpose Compression via Mathematical Functions

Year: 2026
Type: preprint
Abstract: GCMF is a reference encoder and decoder for the General-Purpose Compression via Mathematical Functions lossless format, specified in the Internet-Draft draft-dutta-gcmf-01,which represents a numeric sequence as a compact mathematical function plus a smalldomain descriptor rather than as raw bytes. The reference implementation covers the specification’s LITERAL, predefined-function, CUSTOM (a full 32-opcode bytecode virtual machinewith an automated, bounded-search encoder), and MODULAR representations. It is writtenin dependency-free Python 3, is tested with an automated suite of 34 unit and round-triptests plus a 1,500-trial randomized fuzz run, and is intended for reuse by researchers inminimum-description-length modeling, symbolic regression, and structured-data archival.
