Bu makale iceriginde Suleyman Demirel Universitesi – Bilgisayar Muhendisligi bolumu’nun Yapay Zeka dersi icin gelistirilen Karar Agaci uygulamasinin .Net’de C# programlama dili ile birlikte kullanilarak yapilmis bir ornegini paylasiyor olacagim.
Simdi dilerseniz uygulamanin tasarim ve kod kisimlarina gecelim. Visual Studio’nun Windows Forms Application proje arayuzunde hazirliyoruz.
