About the journal
Discrete & Computational GeometryISSN: 0179-5376 (Paper) 1432-0444 (Online) is an international journal of mathematics and computer science, covering a broad range of topics in which geometry plays a fundamental role. It accepts research articles of high quality in discrete geometry and on the design and analysis of geometric algorithms; more specifically, DCG publishes papers on such topics as configurations and arrangements, spatial subdivision, packing, covering, and tiling, geometric complexity, polytopes, point location, geometric probability, geometric range searching, combinatorial and computational topology, probabilistic techniques in computational geometry, geometry of numbers, and motion planning, as well as papers with a distinct geometric flavor in such areas as graph theory, mathematical programming, real algebraic geometry, matroids, solid modeling, computer graphics, combinatorial optimization, image processing, pattern recognition, crystallography, VLSI design, and robotics.
Instructions to Authors
Manuscript Preparation
Manuscripts for this journal should be printed on only one side of the sheet of paper, double spaced with 1 1/2-inch margins all around. All elements of formulas, also, should be printed whenever possible.
Authors may, if they wish, submit electronically prepared mansucripts in TeX, either by e-mail or on diskettes, with accompanying Postscript files of figures, if any. Follow the instructions set forth here exactly; if, for example, the reference section is incorrectly styled, the value of the electronic submission will be reduced.
Color can be published in the electronic edition of the journal, at no charge to the author, if appropriate electronic files are provided. Color will only be included in the print edition when the author covers the additional expense of color printing. For an exact quote on color printing charges please contact the Production Editor.
If hard copies of figures are provided, each figure (line drawings and graphs) should be submitted on a separate sheet of paper; each diagram should be drawn precisely in India ink, using lines of uniform width, or on a laser printer with resolution at least 300 dpi. The figures should be drawn at twice the size desired: the maximum area for the reduced figures is 4 3/4 ?7 7/8 in., or 122 by 194 mm. All diagrams should be numbered consecutively, and their first mention in the text should be noted in the left-hand margin. Legends should be listed consecutively on a single sheet of paper.
An abstract of the article should be included on the title page. If the full title exceeds 80 characters, an abbreviated version (80 characters or less) of the article title should be provided for use as a running head.
Footnotes other than those referring to the title should be avoided. If they are essential, they should be numbered consecutively and placed at the foot of the page to which they refer.
References to the literature should be listed alphabetically at the end of the manuscript, in the following form:
1. L. Billera and C. W. Lee, A proof of the sufficiency of McMullen's conditions for f-vectors of simplicial convex polytopes. J. Combin. Theory Ser. A 31 (1981), 237-255.
2. P. Erdös, Some combinatorial problems in geometry, in Geometry and Differential Geometry (Proc. Conf. Univ.Haifa 1979), pp. 46-53, Lecture Notes in Mathematics, Vol. 792, Springer-Verlag, Berlin, 1980.
3. G. P. Huijari, An optimal algorithm for the coordinatization of oriented matroids, Discrete Comput. Geom., in press.
4. M. I. Shamos, Computational Geometry, Ph.D. thesis, Yale University, New Haven, CT, 1978.
The Final Manuscript
While authors are permitted to submit articles electronically, they are strongly encouraged to send TeX files of papers once they have been accepted for publication. This will facilitate both the typesetting process, for the publishers, and the proofreading process, for the authors. The remaining instructions pertain to final manuscripts submitted on paper.
In text, words or phrases requiring italic type should be underlined (unless clearly printed in italics). Only the end of a proof should be indicated by an open square.
All letters in formulas, as well as single letters in the text, are automatically printed italic and therefore require no underlining. Where ambiguity would result, please use the following color
Codes for marking:
Greek letters: red
Gothic letters: blue
Script letters: green
Regular (Roman) letters: yellow
Special Roman letters: wavy blue
Boldface: brown
Italics: underline in pencil
Please use pencil for all editorial marks, as the compositor is likely to interpret an ink mark as an element to be printed. If its appearance is ambiguous, underline a capital letter three times. In complicated sections of the text, mark superscripts and subscripts with a caret: (^) Ordinarily subscripts appear directly below superscripts; they should be typed this way, and marked if variation is desired.
The letter O and the numeral 0, and the letter l and the numeral 1 occur frequently. Each appearance of one or zero should be identified. The numeral 1 should be written with a hook and baseline bar. Distinguish between the indefinite article a and the italic letter a used in a mathematical context.
Manuscript Submission
Manuscripts submitted according to these instructions will reduce considerably the cost of charges to the author in proofs. The only corrections to be made in proofs are typographical errors. Should the author wish to correct stylistic or factual errors in proofs, he must absorb the cost. Proofs must be checked and returned within forty-eight hours of receipt.
Fifty free reprints will be forwarded. Additional reprints can be purchased by filling out the reprint order form which will be sent to the corresponding author along with the proofs. Reprints are normally shipped six to eight weeks after publication of the issue in which the item appears. No page charges are imposed.
Authors should submit manuscripts (in triplicate, if by mail) to one of the >Editors-in-Chief
The author's address must be clearly indicated, and the publisher must be notified immediately of a change of address.
Guidelines for Electronically Produced Illustrations for Print
General
- Send illustrations separately from the text (i.e. files should not be integrated with the text files).
- Always send printouts of all illustrations.
Vector (line) Graphics
- Vector graphics exported from a drawing program should be stored in EPS format.
- Suitable drawing program: Adobe Illustrator. For simple line art the following drawing programs are also acceptable: Corel Draw, Freehand, Canvas.
- No rules narrower than .25 pt.
- No gray screens paler than 15% or darker than 60%.
- Screens meant to be differentiated from one another must differ by at least 15%.
Spreadsheet/Presentation Graphics
- Most presentation programs (Excel, PowerPoint, Freelance) produce data that cannot be stored in an EPS format. Therefore graphics produced by these programs cannot be used for print.
Halftone Illustrations
- Black & white and color illustrations should be saved in TIFF format.
- Illustrations should be created using Adobe Photoshop whenever possible.
Scans*
- Scanned reproductions of black and white photographs should be provided as 300 ppi TIFF files.
- Scanned color illustrations should be provided as TIFF files scanned at a minimum of 300 ppi with a 24-bit color depth.
- Line art should be provided as TIFF files at 600 ppi.
* We do prefer having the original art as our printers have drum scanners which allow for better reproduction of critical medical halftones.
Graphics from Videos
- Separate files should be prepared for frames from a video that are to be printed in the journal. When preparing these files you should follow the same rules as listed under Halftone Illustrations.
Guidelines for Electronically Produced Illustrations for ONLINE
Video
- MPEG (.mpg) is the preferred format, but .rm, .avi, .mov, etc. are acceptable.
- No video file should be larger than 2MB. To decrease the size of your file, consider changing one or more of the following variables: frame speed, number of colors/greys, viewing size (in pixels), or compression. Video is subject to Editorial review and approval
