Submission guidelines:
Please submit a full-length paper through Easy Chair conference system: https://easychair.org/conferences/?conf=iccsa20

Submissions must not be published or submitted to a journal and/or conference/workshop with proceedings.

All submissions should be written in English with a six (6) to eight (8) pages paper length including figures and references.

The A4 IEEE templates are to be used.(download the format instruction here).
IEEE provides a set of templates in MS Word and LaTeX format. Please use them to create your paper, but don't modify the style or the format under any circumstances.

Reviewing for the ICCSA'20 Conference is blind to the identities of the authors (Double-blind review). The first page, on whichthe paper body begins, should include the title, abstract, content area, but not the acknowledgments and names or affiliations ofthe authors. The references should include all published literature relevant to the paper, including previous works of the authors.Name your files with care and ensure document properties are also anonymized.

When referring to one’s own work, use the third person, rather than the first person. For example, say “Previously, Harjeck(Harjeck 2012) has shown that...,” rather than “In our previous work (Harjeck 2012) we have shown that....”. Try to avoid includingany information in the body of the paper or references that would identify the authors or their institutions. Such information maybe added to the final camera-ready version for publication.
