What to do on finding a major flaw in a conference paper? Most new findings in Computer Science are now published in conferences. While journals have some policy on reporting of errors in the papers that they have published, I have not seen any conferences having anything related to problems. I have found a major flaw in a paper published in a top conference. So what should I do in this situation?
First contact the authors of the paper, and discuss the issue with them.
When the flaw is small and does not affect their results too much, they might simply put an erratum on their website. When they are unwilling to do so, let it rest (it is a small flaw).
When the error is significant, you might co-publish together with the original authors a new conference article that addresses this (it might even be called 'Erratum on paper XYZ')
