SUBMISSION INFORMATION OF THE NORDIC JOURNAL OF COMPUTING SUBMISSIONS To submit a paper, four copies should be sent to the Editor-in-Chief or directly to the appropriate member of the Board of Editors (see below). Survey and tutorial articles should be sent to the Editor-in-Chief only. The results of the regular papers should be new, and not under consideration for publication elsewhere. Papers should be written in English. Due to space shortage authors should keep the total length to a minimum. Each paper should contain a short abstract, a list of key-words, and a list of classifications using Computing Reviews Categories. Manuscripts should be typed on only one side of the page, double spaced, with wide margins. Figures should be drawn in black ink or should be computer-drawn diagrams of comparable quality. All papers will be acknowledged and refereed. Authors of published papers will be provided with 30 free reprints. Extra reprints may be purchased at cost price if ordered on submission of corrected proof. ELECTRONICALLY PREPARED MANUSCRIPTS Preparation of the manuscript in LaTeX is strongly encouraged. The editorial decision to accept or reject a paper is, however, independent of the technology (computer or a typewriter) used to prepare it. A style file for preparing the final versions of the accepted papers in LaTeX is available from the ftp server of the journal. COPYRIGHT It is understood that, when submitting a paper, the authors confirm that the submitted manuscript has not been published, nor will be simultaneously submitted or published elsewhere. Further, if and when the article is accepted for publication, the authors agree to the automatic transfer of copyright to Publishing Association Nordic Journal of Computing.
