Question

i am getting "Xmin= 4"  answer given 5 please verify

Answer 1

I am getting $5$ only .

Instance after $P_0 \rightarrow P_3 \rightarrow P_2$

Avail : $\{2,x+2,11,8\}$

To suffice need of $P_4$ which is  $\{0,6,4,2\}$ , Min x $=4$ ,

but it won`t suffice the need of $P_1$ which is $\{0,7,5,0 \}$, Min x $=5$

$\therefore $ Max $\{4,5\}=\color{Red}5.$
