Declaration of interest
All authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work.
Submission declaration and verification
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright holder. To verify originality, your article may be checked by the originality detection services. All submitted manuscripts, after being sent to the Iranian Journal of Numerical Analysis and Optimization, will be evaluated by Technical Editors in terms of scope and format of the journal, and all manuscripts submitted to IJNAO are tracked by using "iThenticate" for possible plagiarism.
Changes to authorship
Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion, or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the Editor-in-Chief. To request such a change, the Editor must receive the reason for the change in the author list, and written confirmation (e-mail, letter) from all authors that they agree with the addition, removal, or rearrangement. In the case of the addition or removal of authors, this includes confirmation from the author being added or removed.
Submission to IJNAO proceeds totally online and you will be guided stepwise through the creation and uploading of your files. Please note that even though we apply the PDF file of the manuscript at submission for the review process, but all source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by Email. When a manuscript is returned for revision prior to final acceptance, the revised version must be submitted as soon as possible after the author's receipt of the referees' reports. Revised manuscripts returned after four months will be considered new submissions subject to full re-review.
Iranian journal of numerical analysis and optimization (IJNAO) operates a single-blind side review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding the acceptance or rejection of articles. The Editor's decision is final.
It is strongly recommended to set up the manuscript by Latex or Tex Template(PDF), Template(TEX), using the template provided on the website of the Journal. Manuscripts should be typed double-spaced with wide margins to provide enough room for editorial remarks. We DO NOT accept those manuscripts written in Word documents (such as .docx, .doc and etc.) or any files generated by other word processing software.
Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.
Material and methods
Provide sufficient details to allow the work to be reproduced by an independent researcher. Methods that are already published should be summarized, and indicated by a reference. If quoting directly from a previously published method, use quotation marks and also cite the source. Any modifications to existing methods should also be described.
A Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis.
Results should be clear and concise.
This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.
Title page information
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results, and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if
essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Immediately after the abstract, provide a maximum of 6 keywords, avoiding general and plural terms and multiple concepts. Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes
Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.
Collate acknowledgments in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise.
Please do not:
Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Please submit tables as editable text and not as images. Tables can be placed either next to the relevant text in the article, or on separate page(s) at the end. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be
sparing in the use of tables and ensuring that the data presented in them do not duplicate results described elsewhere in the article.
Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'.
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.
This journal uses a standard numbering style that:
In-text citations: Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given. Example: “..... as demonstrated [3, 6]. Barnaby and Jones  obtained a different result ....
Reference list: Number the references (numbers in square brackets) in the list in the order in which all references should be arranged in alphabetical order by the surname of the first author as examples below:
 Brunner, H. A survey of recent advances in the numerical treatment of Volterra integral and integro-differential equations, J. Comput. Appl. Math. 8 (1982), 213-229.
 Stoer, J. and Bulirsch, R. Introduction to numerical analysis, Springer-Verlag, New York, 2002.
