Battleship Puzzle False Clues
Creates a battleship puzzle with a twist - some numbers are false
Creates a battleship puzzle with a twist - some of the numbers beside the rows and columns are false clues. All of the false clues are either (+1) or (-1) relative to the true clues. Additional information provided to the solver is the annotation of segments of adjacent rows or columns as containing or non-containing a false clue, and the type of the false clue if one exists. For example a riddle can be composed of a standard 10*10 board with an annotation declaring the existance of one plus... -

Grammar based Combinatorial Solver
Solver with Applications in Computer Network Systems Design
The solver performs an exhaustive search on the space defined using simple formal language grammar constructs to identify solutions that meet the objective and constraints. It can be used to easily define complex discrete multi-dimensional combinatorial problems that are otherwise difficult to model using Mixed Integer Linear Programming solvers. The solver does not make any assumptions on continuity of the search space. The solver is implemented in PHP. A GoJS based visualization is provided... -
