Great Sir. You cleared my doubts on degeneracy

[@vipulgoti47]

Thank you my dear friend

[@cakelickinginstrument5312]

very good work sir

[@vipulgoti47]

Thank you

[@shubhamgaurav3279]

Some sources say that in case of a tie in the ratio, we can choose any row arbitrarily. So, why do we apply this method for selecting the key row?

[@vipulgoti47]

It will reduce your iteration steps

[@suyziljackson8202]

what if the coefficient is negative in the slack variables? wont the minimum ratio be negative then?

[@somenmahata465]

Sir is zero can be taken as min ratio?

[@vipulgoti47]

No

[@BikramAdhikari-jz4gr]

Sir is there is any situation where you can choose 0 in minimum ratio?

[@vipulgoti47]

Means?

@@vipulgoti47 any such conditions where we needs to choose 0 as minimum ratio for key row?

what if the minimum ratio of one row is undefined? (12/0)

Skip and go for next step

What happened if key elements will zero

[@vipulgoti47]

It will not happen

@@vipulgoti47 then my calculation is wrong if key element is zero
