I'm struggling with how to say "robust software" in Japanese.
From Wikipedia https://en.wikipedia.org/wiki/Robustness_(computer_science):
In computer science, robustness is the ability of a computer system to cope with errors during execution and cope with erroneous input.
There is no Japanese version of this page. I have searched weblio and Google and found examples of 堅牢なソフトエア and ロバストなソフトエア being used, albeit not very many. There is also this document from The University of Tokyo on robust software. http://www.i.u-tokyo.ac.jp/coe/report/H14/21COE-ISTSC-H14_5_5_1_2.pdf
