Fills a rectangle using given tetris shapes (tetraminos) using an optimized brute force algorithm.
A puzzle can have many different solutions; this solver will stop at the first one. Not all puzzles are solveable.
Created to solve the annoying tetris puzzles in The Talos Principle and Sigils of Elohim.
This is a simple app, created around an original sudoku solver based only on heuristics, not brute force. It's coded in Java/SWT(GUI toolkit). It's an example of MVC and of Visitor, Observer, Strategy, Abstract Factory, Singleton Design Patterns.
HumanSudokuSolver is intended to solve Sudoku puzzles in a way human beings would do (non brute force). It currently solves most of the puzzles I tried and can output a step-by-step solution. Developers who want to contribute are welcome!
A java application for creating, playing and solving SuDoku puzzles of various types. Features both a Swing GUI and command-line operation. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possibility.
