Update 2016/07/13: Official booklet for the 4th IYNT 2016 is posted and went to press. The booklet can be downloaded as a *.pdf file.

Update 2016/07/12: The results of the 4th IYNT 2016 are updated at real time at this page.

Update 2016/03/27: As opposed to past announcements, the dates of the 4th IYNT 2016 are July 16—22, 2016. The LOC 2016 and the GC appreciate greatly your understanding of this unforeseen rescheduling.

Update 2016/02/03: The local webpage is maintained at iynt.ayimi.org.

Update 2015/11/30: Welcome to the local webpage of the 4th IYNT 2016, iynt.ir. The LOC sets the registration deadline to March 30, 2016 as well as the registration fees for Teams and visitors.

Update 2015/11/24: The 4th IYNT 2016 will be held in Shiraz, the City of Roses and Nightingales, on July 10—16, 2016. The competition will be hosted in the premises of Shiraz University, one of the most prominent research-oriented institutions in the country and the region. The dates of the competition are selected such that the IYNT does not overlap with the 29th IYPT 2016 on June 26—July 4 and the IOC meeting of the IYPT on July 4—6. After considering other possible venues of Nowshahr, Tabriz, and previously mentioned capital city of Tehran, the LOC now lands the 4th IYNT 2016 in Shiraz to improve the quality of competition in many aspects. Shiraz is conveniently served by Shiraz International Airport (SYZ). The LOC and GC cordially invite the Teams to pre-register for the 4th IYNT 2016.

Update 2015/09/05: Amended Regulations of the IYNT are approved and adopted. A scan of signed Regulations and the original official PDF are available for download.

Update 2015/06/24: Just minutes after the Semi-Finals of the 3rd IYNT 2015 were over, we released the problems for the 4th IYNT 2016. Our plan to release them on June 25 was revised as FTP access is blocked in the premises of the Closing Ceremony in Belgrade.

Update 2014/09/07: As opposed to the earlier notice of Tehran as the host city for 2015, the IYNT General Council resolved to switch the host for the year 2015. Reduction in travel expenses will significantly widen participation in 2015 and foster the IYNT engagement over the long term.

Invitation, updated 2014/09/07:

The 4th International Young Naturalists' Tournament will be held in Iran in 2016. The local organizer of the IYNT 2016 is Ariaian Young Innovative Minds Institute, AYIMI. We happily invite all teams to the hospitable Persia, a beautiful country with a rich cultural heritage.

In the message confirming the hosting credentials, the IYNT Founder Evgeny Yunosov said, "It is the mutual desire of the GC and of the AYIMI that the IYNT 2016 contributes to the further development of the IYNT movement and enhances its long term interests. We wish that the IYNT 2016 is organized in the best possible manner and takes place under the best possible conditions for the benefit of the participants and educators of the World".

Sixteen Teams joined the competition, including four Teams that did not fulfill age limitation (Ch. 1, IV, 1) and were not eligible for regular Semi-Finals and regular medals. Only nine Teams timely submitted original statements of Invent Yourself and were thus allowed to SF 3, with the brackets for SF 3 determined by applying a Semi-Finals scheme (Ch. 4, II, 1) to the Ranks after SF 2. The brackets for SF 4 depended on Rank R after SF 3, according to a pre-determined rule (Ch. 4, I, 3). The sequence of performances in SF 4, Semi-Finals, and Finals was decided by the Captain winning the Captain's Contest in each Group (Ch. 2, I, 4.) Rejected challenges were counted together for all SFs, including Semi-Finals (a total of 3 rejections not incurring a penalty.) Main problems (Nos. 4—17) were available for challenge in SF 1 and SF 2, Invent youself (Nos. 1—3) were available for challenge in SF 3, and additional problems (Nos. 21—26) were available for challenge in SF 4. As the number of Teams N was above 12, nine regular Teams with the highest Rank R after SF 4 were allowed to the Semi-Finals in three parallel Groups and had secured their Bronze Medals (Ch. 4, II, 1; Ch. 5, I, 4.) There was no challenge procedure in the Semi-Finals (Ch. 4, II, 4.) Three Finalists were three winners (by V) in each Semi-Final group, and in one Group where two Teams emerged with V=1, the Finalist was determined via comparison of Ranks R after Semi-Finals in the said Group only (Ch. 4, II, 1). Main and Invent Yourself problems were available for choice in the Semi-Finals (Ch. 4, II, 4) and Finals (Ch. 4, III, 2.) Priority in the choice of problems for Semi-Finals and Finals was by the Rank R after SF 4 and Semi-Finals respectively, and it was forbidden to pick up a previously reported problem. Finalists had secured their Silver Medals, and only one Team eventually earned V=1 and won Gold Medals (Ch. 5, I, 2.) This Table summarizes only the decisive grading parameters, and the detailed results of the competition can be found here.
