Ushbu maqolada entropiya nazariyasiga asoslangan ma’lumotlarni siqish algoritmlari chuqur tahlil
qilingan. Tadqiqot doirasida Klod Shennonning axborot entropiyasi konsepsiyasi, Xaffman kodlash usuli, arifmetik
kodlash va Lempel–Ziv algoritmlar oilasi kabi asosiy siqish metodlari nazariy jihatdan o‘rganilgan. Maqolada turli siqish
algoritmlarining samaradorlik ko‘rsatkichlari, ularning entropiya chegarasiga yaqinlik darajasi va amaliy qo‘llanilish
sohalari qiyosiy tahlil qilingan. Tadqiqot natijalarida algoritmlarning vaqt murakkabligi, siqish koeffitsiyenti va entropiya
samaradorligi bo‘yicha ikki jadval keltirilgan. Tahlil natijalariga ko‘ra, arifmetik kodlash entropiya chegarasiga eng yaqin
natijalarni berishi, Lempel–Ziv algoritmlari esa amaliy qo‘llanishda yuqori moslashuvchanlikka ega ekanligi isbotlangan.
