Hi
I have a Simplex Algorithm problem
It must be solved with minimum iterations of simplex algorithm tables.
It can be solved with any technique except Matrix.
Can anyone suggest me a way to achieve this?

Problem:
$\displaystyle
Min Z=4{X_1}+X_2+4{X_3}+6{X_4}
$

St:
$\displaystyle
2{X_1}+4{X_2}\ge10
$
$\displaystyle
9{X_2}+3{X_3}\ge18
$
$\displaystyle
-5{X_2}+5{X_4}\ge50
$
$\displaystyle
X_j\ge0
$
$\displaystyle
j=1,2,3,4$

Thanks
