Application Review

1. When the program starts, its start window appears, where we can set the starting variables.

If the data entered by the user is correctly validated, the transition 
to the next window occurs, otherwise errors by type pop up:
  
Error #1 (going beyond acceptable values):

Error #2 (Incorrect data type):

2. Switching to the next window with correct validation of the entered data:

When you click on the "ГОТОВЫЙ ВАРИАНТ"(“READY OPTION”) button, 
the matrix is read from the file system generated during the old iterations 
and goes to the next:

When you click on the "НОВАЯ МАТРИЦА"(“NEW MATRIX”) button, 
a new matrix is generated, uploaded to a file inside the system 
and moved to the next window:

Validation check for the field (EditText Object) repeats:

3. Switching to the next window with correct data validation:

When you click on the "КОНКРЕТНЫЙ МЕТОД"(“SPECIFIC METHOD”) button without 
selecting more than one of the methods (RadioButton objects), the following 
error window will pop up:

Transition with the Method Selection combination + Specific Method/All methods:

When you click on the “NEXT” button without selecting any of the methods 
(RadioButton objects), the following error window will pop up:

4. Switching to the next window with correct data validation:

When you click on the ("СТАРТ")“START” button, the Genethic Algorythm start 
is initialized:

When you click on the “SHOW JSON” button, a JSON file is shown that is fed 
inside the python-script:

5. Switching to the next window when clicking on the "ДАЛЕЕ"(“NEXT”) button:

When you click on the “OK" button, the generation of histograms begins:

Clicking on the histogram takes you to the demo window:
