I am physicist and my research is on Physical/Computational Biology. As most of my colleagues, I am used to visit ArXiv daily to check new articles on my field. Some weeks a go I found a really interesting article with a new method that I would like to implement together with a model I am working with.
At first glance I noted that the parameters used in the article were something strange, but I thought it could be due to the different spatial discretisation employed. However, I changed all my parameters to fit with their method and concluded that they are completely non-sense. Even the most simple case proposed in the article is impossible to achieve using their parametrisation (I was able to reproduce using another set of parameters).
My question is: Have you faced something similar with papers in pre-print servers? Is this something people are used to do in order to avoid other researchers to reproduce their work and advance before the article is published in a journal?
