Also designed and implemented genetic algorithm that fixes user designs or creates new designs from scratch. Added hundreds of unit tests covering many thousands of test cases. Wrote extensive documentation for client developers.
Developed complex Windows Forms control that embeds console-style output in any form. Control offers fast display updates with thread-safe write functions, and numerous formatting, scrolling, and wrapping options. Display buffer can be saved to or restored from file, and mouse-selected content can be pasted to RTF, HTML, or plain text. Finished control is used to develop specialized test apps.
