In the response by O. Steinbock and K. Showalter to a technical comment by D. Gareth Williams (“Minimal path algorithms,” 21 July, p. 418), the word “his” was inadvertently inserted by Science before the word “co-workers” in the second sentence. The authors originally wrote, “We wish to emphasize that path finding from reaction-diffusion waves, which was suggested by Babloyantz and co-workers in 1991 (2) U. A. Sepulchre, A. Babloyantz, L. Steels, in Proceedings of the International Conference on Artificial Neural Networks, T. Kohonen, K. Makisara, O. Simula, J. Kangas, Eds. (Elsevier, Amsterdam, 1991), pp. 1265–1268; J. A. Sepulchre and A. Babloyantz, in Chemical Waves and Patterns, R. Kapral and K. Showalter, Eds. (Kluwer, Dordrecht, 1995), pp. 191–217], represents a mechanism by which physical and biological systems might optimize transit times and distances.” Science regrets the error.
