Properties and design of variable-to-variable length codes
, 2022 Art. 75For the entropy coding of independent and identically distributed (i.i.d.) binary sources, variable-to-variable length (V2V) codes are an interesting alternative to arithmetic coding.

Efficient and compact representations of some non-canonical prefix-free codes
, 2022 For many kinds of prefix-free codes there are efficient and compact alternatives to the traditional tree-based representation. Since these put the codes into canonical form, however, they can only be used when we can choose the order in which codewords ...

New Free Distance Bounds and Design Techniques for Joint Source-Channel Variable-Length Codes
, 2012 International audienceThis paper proposes branch-and-prune algorithms for searching prefix-free joint source-channel codebooks with maximal free distance for given codeword lengths.

Converting an Integer to a Decimal String in Under Two Nanoseconds
Software: Practice and Experience, Volume 56, Issue 8, Page 963-977, August 2026.ABSTRACT Objective Converting binary integers to variable‐length decimal strings is a fundamental operation in computing. Conventional fast approaches rely on recursive division and small lookup tables. The goal of this work is to develop a significantly faster method for this task.

Non-Prefix Free Codes for Constrained Sequences
, 2005 In this paper we consider the use of variable length non prefix-free codes for coding constrained sequences of symbols. We suppose to have a Markov source where some state transitions are impossible, i.e.

Prefix codes: equiprobable words, unequal letter costs [PDF]
, 1996 We consider the following variant of Huffman coding in which the costs of the letters rather than the probabilities of the words, are nonuniform: "Given an alphabet of r letters of nonuniform length, find a minimum-average-length prefix-free set of n ...

Representing Variable-Length Codes in Fixed-Length T-Depletion Format in Encoders and Decoders
, 1997 T-Codes are a class of variable-length codes. Their self-synchronisation properties are useful in compression and communication applications where error recovery rather than error correction is at issue, for example, in digital telephony. T-Codes may be

Ecology and Evolution, Volume 16, Issue 3, March 2026.PhyloRef processes complete mitochondrial genomes with optional multi‐gene concatenation to flag three categories of phylogenetic anomalies based on tree topology and annotates ambiguous sequences with “similar_to=” labels. The workflow successfully curated 7600+ chondrichthyan and actinopterygian sequences from NCBI, identifying and removing 410 ...

Making Multimethod Latent State–Trait Models for Random and Fixed Situations Accessible: A Tutorial
Journal of Personality, Volume 93, Issue 5, Page 1018-1041, October 2025.ABSTRACT Objective As more researchers employ longitudinal research designs, which integrate multiple methods and multiple (fixed) situations, the need for appropriate analytical methods arises. Method Multimethod latent state–trait models for random and fixed situations (MM‐LST‐RF; Hintz et al. 2019) provide a means with which person characteristics, (

Journal of Engineering Education, Volume 114, Issue 3, July 2025.Abstract Background Courses in engineering often use peer evaluation to monitor teamwork behaviors and team dynamics. The qualitative peer comments written for peer evaluations hold potential as a valuable source of formative feedback for students, yet little is known about their content and quality. Purpose This study uses a large language model (LLM)
