Computational Science and Engineering and Source Code Evolution

软件对于研究计算科学与工程（CS&E）问题越来越重要。为了满足科学家和工程师的需求，CS&E软件需要是高质量的软件，然而，在这种情况下使用的许多软件是由没有受过正规计算机科学或软件工程培训的科学家或工程师开发的。这些是专业的最终用户开发人员，他们是软件领域的专家，但是他们并不认为自己主要是软件开发人员。

Software is increasingly important for studying computational science and engineering (CS&E) problems. To serve the needs of scientists and engineers, CS&E software needs to be high quality software, however, much of the software used in this context is developed by scientists or engineers with no formal computer science or software engineering training. These are professional end-user developers who are experts in the domain of the software, but who do not view themselves primarily as software developers.
