Ushbu maqolada tabiatda uchraydigan jarayonlar: issiqlik tarqalishi, tor tebranishi, sterjen tebranishi, mayatnik tebranishi, magnit maydoni impulsi va hakazolar. Har qanday tabiiy protsess o’lchanganligi sababli uni modellashtirishdan hosil bo’lgan masala taqribiy yechiladi. Biz yechimni protsessni kuzatish (bir nuqtada o’lchash) yordamida hisoblashga harakat qildik. Bunda masala uchun qo’shma operator tuzilib, nokorrekt masala (boshlang’ich qiymat yo’q holat) shartli korrekt xolatga o’tkaziladi. Natijada matematik fizika masalasi ekstremum masalasiga keltirib yechim chekli sondagi algebraik tenglamalar sistemasiga keltiriladi
