- 14 October 2000
- Updated the IOI SC page.
Copied the
tasks
for IOI'89 through IOI'93 from the ftp server to the http server
(some people had difficulties accessing our ftp server).
- 7 September 2000
- Added the
IOI Regulations as approved
at IOI'98 and IOI'99.
Reorganized the collection of
past and current IOI Regulations.
- Expanded the
Guidelines for IOI Participants.
- Did many small things, for which I did not have the time to
summarize them here (such as pages for the
IOI Scientific Committee
and IOI Software Team).
- 22 December 1999
- Upgraded books search facilities on
pages with recommended literature for self-study.
NOTE: Most of the changes I make are small, and are no longer announced
here.
Instead, there is a table with announcements on the home page.
(E.g. about the IOI2000 web site.)
- 23 November 1998
- Updated information about
IOI'99 in Turkey.
Added a ``button bar'' [ IOI: ... ]
on IOI home page
with direct links to important IOI information.
Updated the member list of the
International Committee for the IOI.
- 14 July 1998
- Made numerous small changes, such as new recommendations on the books pages,
and the IOI'97 contest material (much of it, but not all).
Added a banner on the home page to my experiment with an applet (Java 1.1)
that animates a reactive IOI programming task.
The applet is certainly not finished, but it performs adequately to
help investigate and understand this problem.
- 17 February 1998
- Did some maintenance on the IOI Secretariat web site over the last month.
Consequently some files have been moved.
The stable entry points are
Background color has been explicitly set to white on many pages.
Shortcuts added for each IOI'yy on the
IOI Secretariat's Home Page.
Information about
Mathematics&Informatics Quarterly updated.
The issue of mirroring the IOI Secretariat has been brought up at the
GA and IC meetings in Cape Town (Dec. 1997).
Eventually this will be necessary.
No immediate steps have been taken.
In the mean time, a Taiwan-based mirror
has appeared.
- 22 December 1997
- Because of reliability problems with our regular WWW server www.win.tue.nl,
I have made a copy of all olympiad material to a new server named
olympiads.win.tue.nl.
It is recommended that you change your URLs for olympiad material to
http://olympiads.win.tue.nl/ioi/.
The information at the new location will eventually be restructured to take
advantage of having a server dedicated to olympiad material.
Currently, however, it will remain as it was.
The old server will remain in operation, but may not be reachable from
time to time.
When the olympiad material disappears from the old server, it will have
a page that redirects you to the new location.
- 10 December 1997
-
- Added an overview of mailing lists.
- During IOI'97, some pictures were added.
- The IOI'97 competition material
(tasks (i.e. day overviews, descriptions, libaries),
test data (and library sources), documented solutions, results, etc.)
will be made available via the IOI'97 web site, and later copied to
the IOI Secretariat.
- 24 November 1997
- Some of the recent changes are the following.
- The IOI Secretariat now has its own domain name:
http://olympiads.win.tue.nl/ioi/.
The old address (http://www.win.tue.nl/ioi/) will remain to work.
- Added links to other science olympiads on top of IMO, IPhO, IChO,
IBO, and IAO pages.
- Added
comp.programming.contests
newsgroup and
link for Mind Sports Olympiad
on contents page.
- Added link for 8th IBO (1997) on
IBO page.
The IBO'97 site does not yet include the problem set,
but that is in prepaeration.
- 6 October 1997
- Started a new IOI mailing list to replace
the old IOI mailing list located in Hungary <ioi@inf.bme.hu>,
which has been out of order for some time now.
All subscribers that could be traced for the old mailing list, have been
subscribed to the new list today (and they should receive a welcome message
by e-mail).
E-mail addresses that resulted in error messages during the subscription
procedure have subsequently be unsubscribed.
To find out whether you are subscribed to the new IOI mailing list you
can send the following message to <majordomo@win.tue.nl>:
which
<e-mail address>
end
Posting to the new IOI mailing list is not possible until the resubscription
procedure has been completed.
Availability of the list for posting will be announced at the
IOI mailing list page.
- 20 August 1997
- Added/reconfirmed links for
IPhO 1998 (Iceland),

International Astronomy Olympiad (IAO).

introducing subdirectories for IMOs from 1993 to 1997.
The IMO 1997 problems and results are now available.
Changed the way that the "NEWS button" on the home page is linked to
the file with changes.
The change log is (still) in a file named changes.html
,
but there is now a (UNIX) link (also known as an alias) of the form
dd-mm-yy.html
to this same file.
This alias is used on the home page to link to the change log.
In that way, whenever the change log is updated, the link to it
will change, and when you access the home page, the link will be
marked unvisited if you have not seen the most recent changes.
Added minutes for the 13th and 14th
meetings of the International Committe
of the IOI.
- 29 July 1997

International Committee.
- 3 July 1997
- The IOI Mailing List is currently
out of order, due to a crashed disk at inf.bme.hu (also see 20 May 1997).

but without succes so far.
If you have more information, please let me know.
- 12 May 1997
- Added a link to the Latvian Olympiad in Informatics on the
national olympiads in informatics page.

accessible. Arsène von Wyss has set up a
mirror page for
the Programming Contests Archive to alleviate this problem somewhat.
- 24 March 1997
- The URL of the IOI Secretariat has changed from
http://www.win.tue.nl/win/ioi/ to
http://www.win.tue.nl/ioi/
(i.e., `win' has been removed).
For the time being our server will automatically translate
requests for the old URL into the new URL.
I suggest, however, that you update any hyperlinks aimed at
the IOI Secretariat to use the new URL.

can order the book conveniently and quickly through the Internet.
