Consider a two$-$objective minimisation problem solved by NSGA$-$II generating the following combined parent$/$offspring population

$($objective values shown for all $16$ members, i$.$e$.$ M$1$~M$16)$ at one of the iterations:

Table Q$5$

What is the size of the population at the end of each iterations?

During the current iteration, the following members: $\{$M$2,$ M$3,$ M$4,$ M$7,$ M$14,$ M$15\}$ from Table Q$5$ belong to Rank $2.$
