SurGe is a computer program which enables to generate surface as an interpolation (approximation) function of two independent variables. The program has the following basic features:
> Implements an interpolation / approximation method called ABOS.
> Basic input is a simple ASCII file containing X, Y and Z coordinates of points irregularly spaced in some region.
> The surface can be defined not only by points, but also by spatial (three-dimensional) polylines.
> So called fault lines can define discontinuity in generated surface.
> Generated surface can pass through points exactly or can be approximative.
> Smoothness of resulting surface can be controlled by one parameter.
> Large data sets (with noise) can be effectively filtered.
> Quality of resulting surface is comparable with surface created by Kriging or Minimum curvature method.

Minestein is a Minesweeper game that has puzzles which can be solved entirely by logic. It ha a two stage hint system and can provide puzzles with a minimum difficulty rating as measured in 3BV scores. The source code is included. It can also provide random puzzles like traditional Minesweeper games.
Configurable options
Users can set:
the grid size
the number of mines
the minimum 3BV score
select sets of standard puzzles
to use puzzles that can be solved by logic
to use puzzles that require guessing
which algorithms are used to create the puzzles and provide hints
Toolbar
The toolbar includes buttons to request a hint.
The first click identifies a logically solvable cell.
Then a second click sets the answer for the cell if the user cannot work out the solution.
The toolbar also has buttons to provide the answer for a cell or the whole grid, and to start a new game
