License tagging for Image:Nonlinear model.png
Thanks for uploading Image:Nonlinear model.png. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:
 * Image use policy
 * Image copyright tags

This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Media copyright questions. 19:09, 11 September 2007 (UTC)

Managing a conflict of interest
Hello, Jhedengren. We welcome your contributions, but if you have an external relationship with the people, places or things you have written about in the article Gekko (optimization software), you may have a conflict of interest (COI). Editors with a COI may be unduly influenced by their connection to the topic. See the conflict of interest guideline and FAQ for organizations for more information. We ask that you:


 * avoid editing or creating articles about yourself, your family, friends, company, organization or competitors;
 * propose changes on the talk pages of affected articles (see the request edit template);
 * disclose your COI when discussing affected articles (see WP:DISCLOSE);
 * avoid linking to your organization's website in other articles (see WP:SPAM);
 * do your best to comply with Wikipedia's content policies.

In addition, you must disclose your employer, client, and affiliation with respect to any contribution for which you receive, or expect to receive, compensation (see WP:PAID).

Also please note that editing for the purpose of advertising, publicising, or promoting anyone or anything is not permitted. Thank you. Largoplazo (talk) 00:15, 28 April 2018 (UTC)

Proposed deletion of Gekko (optimization software)


The article Gekko (optimization software) has been proposed for deletion&#32;because of the following concern: "I found no substantial and independent coverage of this software to meet WP:GNG, once I excluded from a Google search a couple of phrases shared in common on a number of websites (suggesting promotional copy) and a mining company in Canada."

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

COI and additional information on GEKKO
Gekko software is freely available with the Apache license. It is developed by Logan Beal at Brigham Young University under the National Science Foundation Grant (NSF #1547110) entitled EAGER: Cyber-Manufacturing with Multi-echelon Control and Scheduling. I created this article as Logan's research advisor and to fulfill NSF's objective of having broader impacts and disseminating the research for others.

As with any new developments, there are concerns about the notability of the subject. The initial reviewer did not find substantial references through a Google search and suggests that the article be deleted. Granted, the software is new and does not have a long history of references. However, this software is the successor to the APMonitor Optimization Suite that is extensively cited in the literature and is currently one of the most popular packages for dynamic optimization. Below are some additional search routes to establish GEKKO notability:


 * Search Google: "GEKKO Optimization YouTube"
 * Search LinkedIn for posts related to GEKKO
 * Used in popular Dynamic Optimization Online Course
 * Available on PyPI: https://pypi.org/project/gekko/
 * Listed on apopt.com
 * Discussions on Stack Exchange
 * Discussions on the APMonitor Google Group
 * Several new references are listed on NSF's page for project #1547110

Better source request for File:Gekko logo.png
Thanks for your upload to Wikipedia: You provided a source, but it is difficult for other users to examine the copyright status of the image because the source is incomplete. Please consider clarifying the exact source so that the copyright status may be checked more easily. It is best to specify the exact Web page where you found the image, rather than only giving the source domain, search engine, pinboard, aggregator, or the URL of the image file itself. Please update the image description with a URL that will be more helpful to other users in determining the copyright status.
 * File:Gekko logo.png

If you have uploaded other files, consider checking that you have specified their source in a complete manner. You can find a list of files you have uploaded by following [ this link]. If you have any questions please ask them at the Media copyright questions page or me at my talk page. Thank you. ShakespeareFan00 (talk) 13:10, 28 April 2018 (UTC)

Nomination of Gekko (optimization software) for deletion
A discussion is taking place as to whether the article Gekko (optimization software) is suitable for inclusion in Wikipedia according to Wikipedia's policies and guidelines or whether it should be deleted.

The article will be discussed at Articles for deletion/Gekko (optimization software) until a consensus is reached, and anyone is welcome to contribute to the discussion. The nomination will explain the policies and guidelines which are of concern. The discussion focuses on high-quality evidence and our policies and guidelines.

Users may edit the article during the discussion, including to improve the article to address concerns raised in the discussion. However, do not remove the article-for-deletion notice from the top of the article. Largoplazo (talk) 15:57, 29 April 2018 (UTC)

Response to Gekko (optimization software) for deletion
Are the editors willing to consider other sources besides Google? Gekko publications have a longer history of publication in the scientific (rigorously peer-reviewed) literature. The Gekko name was not used during the development of the software (similar to how Intel has a different name for chips when in development than in production). The NSF Award page (https://www.nsf.gov/awardsearch/showAward?AWD_ID=1547110) gives several references:

Logan Beal (Gekko creator) and I were editors on a new special issue book that was recently published that highlights developments in this area from multiple contributors:

A few additional contributions may appear soon but are currently under peer review or development:
 * Facebook internet drone design is generated by Gekko: https://scholarsarchive.byu.edu/cgi/viewcontent.cgi?article=3086&context=facpub
 * Petrobras (in Brazil) is developing improvements to distillation with Gekko (see bottom of http://apmonitor.com/do/index.php/Main/ProjectLab):
 * Statoil is developing improvements to heat exchangers with Gekko
 * University of Utah is developing Gekko for energy system optimization of district energy system
 * Self-balancing robots with Gekko: http://apmonitor.com/do/index.php/Main/InvertedPendulum

The notability will continue to improve as additional independent articles are published. The peer review process and publication can take a while for any new contribution but it is currently on track to have a substantial body of references by the end of 2018. Perhaps this would be a better target for creating a new Gekko page on Wikipedia but it seems that there are many other Wikipedia articles in this area that have many fewer citations. See, for example, many of the software packages that are listed in the Mathematical Optimization Software list at the bottom of the Gekko (optimization software) page on Wikipedia. I understand that new articles need additional scrutiny but the Gekko article is clearly ahead of many of those that already exist in terms of citations in the academic literature. I will update the Gekko article to include additional citations to meet the notability requirements.
