> Unfortunately the actual paper at http://www.sciencedirect.com/science/article/pii/S0022096516.. http://www.sciencedirect.com/science/article/pii/S0022096516.... is paywalled in the usual way. Searching for "title of article" PDF is usually pretty effective (and is in this case ;-) ). In CS you'll find a PDF hosted on the author's home page like 99% percent of the time. Other fields are more spotty, but this approach is still pretty effective.
