Ustun asosining elementlari (B)

Oldingi iteratsiyaning hisob-kitoblari natijalari uchun biz x ₆ asosidan o'zgaruvchini olib tashlaymiz va uning o'rniga x _{1 ni} qo'yamiz . Boshqa barcha hujayralar o'zgarishsiz qoladi.

Cb ustun elementlari

Ushbu ustunning har bir katakchasi mos keladigan qatordagi asosiy o'zgaruvchiga mos keladigan koeffitsientga teng.

Cb₁ = 24;

Cb₂ = 20;
Cb₃ = 25;


O'zgaruvchan o'zgaruvchilarning qiymatlari va P ustuni
(Oldingi iteratsiya ma'lumotlari dastlabki ma'lumotlar sifatida olinadi) Barcha kataklarni bazaga kiritilgan o'zgaruvchiga mos keladigan nol bilan to'ldiring:
(Rezolyutsiya elementi o'zgarishsiz qoladi)


^x 1,1 <sup>= 0;


x</sup> 2,1 ^{= 0;}

Biz oldingi jadvaldagi hal qiluvchi element bilan qatorni joriy jadvalga o'tkazamiz, uning qiymatlarini hal qiluvchi elementga elementlar bo'yicha ajratamiz:

Qolgan bo'sh katakchalar, hisoblar qatori va Q ustunidan tashqari, hal qiluvchi elementga nisbatan to'rtburchaklar usuli yordamida hisoblanadi:
