Algorithm 1: Main Procedure of the Proposed NTSEA

Input: population size N, maximum function evaluations ( $T_{\max }$ )

Output: the final population P

1: $P\leftarrow Initialize(P)$

2:Generate N uniformly distributed m dimensional unit vectors as $Z\leftarrow \{z^1,z^2,\cdots ,z^N\}$

3: $z\leftarrow Z^{\min }$

4: while $t<T_{\max }$ do

5: Grid setting for P

6: Fitness assignment for P

7: $MP\leftarrow Matingselection(P)$

8: $P^{\prime }\leftarrow GenerateOffsprings(MP)$

9: $Q\leftarrow P\cup P^{\prime }$

10: $P\leftarrow Environmentalselection(Q)$

11: end while
