Discrete Mathematics Letters is an open-access, peer-reviewed, and international e-journal, which aims to provide a forum for the rapid publication of original articles, consisting of at most eight published pages, in all areas of discrete mathematics. Manuscripts concerning all those areas of discrete mathematics that are closely associated with the research interests of the Editorial Team‘s members are preferred. Manuscripts contributing some non-trivial progress in the solution of existing problems and conjectures, as well as those consisting of an alternative/short proof of some well-known result of discrete mathematics, are especially welcomed. This journal also publishes mini-reviews of high quality. The page limit for mini-reviews is thirty pages. Moreover, this journal occasionally publishes autobiographical notes and interview articles (concerning well-known discrete mathematicians) without any page limit.
