## 4 Results
### Primary Journals, Highly Cited Articles, and Highly Effective Academicians
There are two scholars from Greece ([PERSON] with 28 papers and [PERSON] with 26 papers), two scholars from Iran ([PERSON] with 25 papers and [PERSON] with 17 papers), one form the UK ([PERSON] with 15 papers), one from Japan ([PERSON] with 14 papers), one from Israel ([PERSON] with 13 papers), one from Cyprus ([PERSON] with 13 papers), one from China ([PERSON] with 10 papers), and one from the USA ([PERSON] with 9 papers). [PERSON] rated first (n = 519), followed by [PERSON]. (n = 513), based on the total number of citations. The number of citations by other scholars in Table 4 ranges from 114 to 470. Consequently, these scholars' h-indices are between 5 and 13. The first researchers on structural systems with a seismic design using evolutionary computation, metaheuristics, and nature-inspired algorithms since 1986 were [PERSON] and [PERSON] The next publications after this study were in 1992 and were conducted by [PERSON] and [PERSON] Both studies were conference papers. Subsequent studies began to intensify in the 2000s. Figure 4 displays the collaboration network of academics who have published two or more times. An author is represented by each node. The number of articles determines the size of the nodes, and the degree of collaboration between nodes is shown by the lines connecting them. Collaborating scholars are coded in various colors and placed within \begin{table}

Table 3: The ten most cited articles. the same clusters. One can identify a number of groupings that were created around the scholars listed in Table 4. [PERSON] and [PERSON] are at the core of the largest group, which consists of six academics. Table 4 also shows the formation of other groups around other scholars: the red group is established around [PERSON]; the orange group is formed around [PERSON]; the green group is formed around [PERSON]; and the pink group is formed around [PERSON] There are extremely few writers in the remaining groupings, and only four groups have more than three scholars in them.
