Graph neural network-based virtual network function deployment optimization (vol 31, e2164, 2021)

In Kim et al,1 the following errors were published on page 10 and Tables 6 to 10. On page 10, an equation label (13) was inadvertently added on an incorrect displayed equation. Hence, the succeeding equations and corresponding citations were renumbered accordingly. While on Tables 6 to 10, the word “Data center” was mistakenly changed to “Data left” throughout the article. The online version has been corrected. We apologize for this error.
