[Help-glpk] Kakuro, Futoshiki Ficki, NumberWorkout, and other Sudoku-like puzzles

[Nigel Galloway]

There are several number problems which rely on certain blocks of 
cells on a board having one, or more, of the following properties:

➢they sum to a certain value;
➢each cell is unique within the block;
➢the sum of one block equals the sum of the other;
➢the sum of one block is less than the sum of the other.

This paper presents a Model using mathProg to solve these problems 
and gives examples for:
miniSudoku,
SudokuX,

SuperSudokuX,
Kakuro,
Sumdoku,
Futoshiki Ficki,
and NumberWorkout.
