Authors are invited to submit papers (extended abstracts) describing original research of theoretical or practical significance to algorithms and computation. Papers should not exceed 12 pages in LNCS style. Papers significantly shorter than 12 pages are also welcome. If the authors feel that more details are essential to substantiate the main claim of the paper, they may include a clearly marked appendix that will be read at the discretion of the Program Committee. Only electronic submissions via Easychair will be allowed (Link: https://easychair.org/conferences/?conf=walcom2018). Submitted papers must describe work not previously published. They must not be submitted simultaneously to another conference with refereed proceedings or to a journal.
