Programs
SFOLD
SFOLD calculates sfermion decays in the MSSM at full one loop level. Programmed in Fortran 77, C and Mathematica. Downloadable here.
Surface generator
Run me!It's a 3D surface generator.
Scene
Run me!It's a 3D scene with simple objects. You can walk through the scene (and throgh the objects). I have not used any graphics library like DirectX or OpenGL. All the rasterization I did by myself. Ilumination is included, shadows not yet. The code still needs some speeding up.
Huffman Coding
Run me! source filesHuffman coding.
Hashing
Run me! source filesCollisions are treated by chaining.
Skeleton 2D
Run me! source filesWe used thinning technique. The program may not create connected skeleton.
Trained Sin
Run me! source files
We train the neural network to calculate the function (1 + Sin(x))/2. We used the
back propagation algoritm.
Note: When putting real number for the error, you should may use comma instead of dot.
Trained Sum
Run me! source filesThe program is supposed to calculate the sum of five numbers. The sum results from training the linear function f = w0*x0 + w1*x1 + w2*x2 + w3*x3 + w4*x4 + w5. We used the iterative numerical technique called gradient descent. Please, use intergers for input parameters.
Trained Sum 2
Run me! source filesThe program is supposed to calculate the sum of five numbers. The sum results from training the linear function f = w0*x0 + w1*x1 + w2*x2 + w3*x3 + w4*x4 + w5. We used the Newton method. Please, use intergers for input parameters.
Mandelbrot Set
Run me! source filesProgram displays the Mandelbrot set. You can also move and zoom the view.
Subsequence
Run me! source files
This program finds the biggest subsequence from string s2 in string s1.
Example: s1 = AABACCA, s2 = ABDC, biggest subsequence = ABC
The following table should be sufficient to understand how the program works:
| A | A | B | A | C | C | A | ||
|---|---|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| A | 0 | 1 ↖ | 1 ↖ | 1 ← | 1 ↖ | 1 ← | 1 ← | 1 ↖ |
| B | 0 | 1 ↑ | 1 ↑ | 2 ↖ | 2 ← | 2 ← | 2 ← | 2 ← |
| D | 0 | 1 ↑ | 1 ↑ | 2 ↑ | 2 ↑ | 2 ↑ | 2 ↑ | 2 ↑ |
| C | 0 | 1 ↑ | 1 ↑ | 2 ↑ | 2 ↑ | 3 ↖ | 3 ↖ | 3 ← |
If the letters are equal the arrow points up-left, otherwise the arrow points to the bigger number (if numbers equal you can choose between up and left).
Heapsort
Run me! source filesClassic heapsort.
Moving the square
Run me! source filesWhen you click on the square you can drag it.
Connection to SQL
source filesYou can have a look on how to connect to a database and how to retrieve data from a table in C#. The table in the source file is named 'Vendor' and has two columns: 'V_Code' and V_Name.
Serialization and C++
source filesThe C++ language provides limited support for file processing. C++ supports saving only values of primitive types such as short, int, char double. In this example we show how to save and read object comprising also dynamical array.
