1 Correction to: Computational Optimization and Applications 10: 283–320 (1998) https://doi.org/10.1023/A:1018321307393 and 73:1019 (2019) https://doi.org/10.1007/s10589-019-00098-6

The original version of this erratum unfortunately contained an error in DOI of Monthly Weather Review. The correct DOI is https://doi.org/10.1175/1520-0493(1997)125<2460:AOANAN>2.0.CO;2

Hence, the corrected erratum text is as follows:

It has come to our attention that the “Adjoint Newton Algorithm” has been published within the following papers

Wang, Z., Droegemeier, K.K., White, L. & Navon, I.M. Monthly Weather Review (1997) 125: 2460. https://doi.org/10.1175/1520-0493(1997)125<2460:AOANAN>2.0.CO;2

and

Wang, Z., Droegemeier, K. & White, L. Computational Optimization and Applications (1998) 10: 283. https://doi.org/10.1023/A:1018321307393

The authors acknowledge that Wang et al. (1998) was submitted two years prior to publication and was therefore intended to precede Wang et al. (1997), and they acknowledge that Wang et al. (1997) was the first to publish the algorithm.
