    Sudoku Game Solver Generator

    Sudoku Game Solver Generator

    Standalone Complete Sudoku puzzle Game Solver Generator for Windows

    This is the most complete and standalone Sudoku puzzle suite for Windows. It includes comfort playing with undo steps and powerful Sudoku generator with different difficulty levels. Also you can create Sudoku game manually and print it on an A4/Letter paper. Tutorial mode with solving hints for newbies is included too. Also there is High Score table and built-in timer for professional players. The Sudoku generation algorithm used by this app is my ultimate proud. Primarily it was based on a Deep Neural Network. But I analyzed more than 100 scientific publications on Sudoku generation problem and have reduced the Deep Neural Network to a relatively simple and very elegant deterministic algorithm that works pretty fast. As a result, the app can generate Sudoku fields in 7 difficulty levels from 'Yellow Belt' to 'Sudoku Game Jedi Master'. The application supports Quick Start mode, see features below [QS Step 1] and [QS Step 2] (buttons in an application window).

    Gtk3.7 and Gtkmm3.6 for Windows

    Gtk3 stack for Windows Vista/7/8 : Gtk+ 3.7.2 and Gtkmm 3.6.0

    This is the Gtk 3.7.2 stack installer; It includes all Gtk dependencies required for Gtk+ and Gtkmm. The Gtk+ stack was built in version 3.7.2 and finally, the Gtkmm stack in version 3.6.0.1. Each library was built with Visual Studio 2012 in 32 and 64 bits without the Windows XP support. This build passes many test on Windows Vista, 7 and 8 with many applications and official samples built with MSVC 2012 on Windows 7, with MSVC 2010 and with MSVC 2008 on Vista and MSVC 2012 on Windows 8. The installer allows the user to choose the most appropriate installation for him (only Gtk+, only DLL, only 32 bits, full installation 32/64 bits with Libs and headers, etc...) Enjoy !

    Random Bits Forest

    RBF: a Strong Classifier/Regressor for Big Data

    We present a classification and regression algorithm called Random Bits Forest (RBF). RBF integrates neural network (for depth), boosting (for wideness) and random forest (for accuracy). It first generates and selects ~10,000 small three-layer threshold random neural networks as basis by gradient boosting scheme. These binary basis are then feed into a modified random forest algorithm to obtain predictions. In conclusion, RBF is a novel framework that performs strongly especially on data with large size.

    ebfformat

    ebfformat

    An Efficient Binary data Format

    EBF, which stands for Efficient Binary Format, is a binary file format for reading and writing binary data easily. Reading writing routines are currently available in C,C++,Fortran,Java, Python, IDL, MATLAB. A program called ebftkpy which has a set of utility functions to work with the .ebf files , e.g., viewing the contents and getting a summary, is also provided. The EBF specification is designed to be concise and easy to understand to make it easier for others to write their own code if needed. It is also designed to simplify the programming of input output routines in different programming languages. In a nutshell an EBF file is a collection of data objects. Each data object is specified by a unique name and a single file can have multiple data objects. Each data object is preceded by a meta-data or header which describes the binary data associated with it. Among other things, this header allows the files to be portable across systems with different endianess.

    JSON Parser

    JSON Parser

    JSON Parser written in C that outputs JSON into D-List list objects

    JSON parser is a highly efficient JSON data decoder written in C, that parses JSON data into a form that is very easy to use from within C code. You only need to include the json-parser.h file in your source code. If your project does not already incorporate D-List, you will also need to include dlist.h The JSON parser package also includes a JSON validator that does not parse or create resources, but allows the caller to validate JSON data from unknown sources, prior to any parsing attempts. The JSON data is returned to the caller as a set of hierarchical D-List list objects, that make the data very easy to manage, sort, search or use, and easy to remove when done. Package includes a JSON textural generator which will create JSON grammar data blocks from hierarchical D-List representations of JSON data. The package also includes a variety of support functions to allow C code to easily find, add, and modify JSON values and members in D-List hierarchical structures.
