Gams: January 2014

Merhaba uzuuuuun zamandır burada yazmıyordum. Fakat aldığım mailler sebebiyle buraya yazma ihtiyacı hissettim. Çünkü elime çok gams dosyası geçti bunları sizlerle paylaşmak istedim.

Şimdi sorunun hatalı halini alalım.

Açıklamalar

-Görüldüğü gibi bir çok uncontrooled set zımbırtısı var bunun çözümü için kısıtları değiştirmek yeterli olacak
- Bir başk hata ise çözüm tipinin yanlış girilmesi o hata konusunda bir bilgim yok ama DNLP yapınca geçti.

düzgün kod aşağıdaki gibidir.
