One platform to build, fine-tune, and deploy ML models. No MLOps team required.
Access Gemini 3 and 200+ models. Build chatbots, agents, or custom models with built-in monitoring and scaling.
This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.
I want to test some ways to store the data for the Huffman Tree
Lectures on Huffman Code mostly focus on creating the Huffman Tree and converting the given data into the new bitmap. But what about the informations needed to create the Huffman Tree? They must be stored as well. With this project I want to test some possibilities to store these data.
gmp,h is needed to compile.

libarxx is a C++ archiver with advanced features, like data synchronization and merging of multiple archives. It provides an object-oriented view on a directory tree of data items and allows versioning, compressing and structuring in multiple ways.
Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.
The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.The algorithm is based on a set of template classes : Cell(SYMBOL, WEIGHT), Node(
Numerically estimate an efficiency of code construction algorithms. Randomly generate n binary words of length m with minimum Hamming distance d and create a prefix code (= retrieval tree) from them. Based on PhD work.
garchiver is an archiver for Gnome. It has a tree interface that lets you
navigate through your archives very easily, as well as the classic WinZip
interface. It also has full drag and drop support.
