Browser and device compatibility
Please consult this information to ensure that your system is compatible with the competition environment and you can concentrate on solving the problems during the competition (or marking them after) instead of having to work around technical issues.
The compatibility of the competition environment is still being thoroughly tested with different systems and the information here will be updated twice a week. Last updated: 22/09/2020.
PC (Windows 10 Home)
On PC the environment was tested and worked well on latest versions of Edge (85.0.564.44 (Official Edition) (64-bit)), Google Chrome (85.0.4183.83 (Official Edition) (64-bit)), Firefox (80.0.1 (64-bit)) and Opera (70.0.3728.178, Windows 10 64-bit). Do not use Internet Explorer, the environment will not work! Firefox saves the answers without any problems, but the student user can answer at one age level and cannot answer at other age levels.
The competition environment also works in the older version of Firefox (79.0.0 (64-bit)).
Warning! If cookies are blocked, in Microsoft Edge, Google Chrome, Firefox and Opera the competition environment does not work. Opera Ad Blocker and Tracker Blocker do not interfere with the competition environment while running.
Warning! From one IP address of one router, one user can log in with multiple devices without system failure.
On PC, screen resolutions 1366 * 768 and 1280 * 720 work fine in the above browsers, although some inconveniences are seen. Not all images fit on the screen, some menus require scrolling from end to end, and in an ORDER type task, not all may be visible at once, and the panels must be moved in several intermediate stages.
Using iPhone and Android smartphones for the competition is technically possible, but there are a number of problems.
On iPhone (iOS 13.6.1) the tested browsers are Edge (45.8.0), Safari (13.1), Firefox (28.1) and Chrome (85.0.4183.92). The observed problems are mainly related to the small size of the phone screen, which does not fit pictures, text and other objects properly.
In general, running Theory and Data Analysis round problems should be fine on iPhone browsers, but they will not look as good as on PC and some figures/plots might need zooming or use of Landscape mode to fit on screen. Observation round problems are currently showing some issues, which are being worked on. In case it is not possible to solve them, it is advisable to use PC-s for this round.
CANVAS type problem can be seen at the bottom of the screen, need to scroll down to see it. Added images in the problem are small in the phone’s Portrait mode. The objects’ radii are large. In Landscape mode, the problem images are even smaller and the objects’ radii even larger than in Portrait mode.
MATCH type problem can be seen at the bottom of the screen, need to scroll down to see it. It won’t fit on the screen in Portrait mode. Using Landscape mode helps fit the problem on the screen, but still need to scroll down to see it. In Portrait mode, categories might get hidden behind the screen so that one wouldn’t think there are any more.
ORDER type problem: it might be inconvenient to drag the answers when there are a lot of objects to order. It’s not always possible to move up the page and drag the object at the same time. ORDER type problem works better in Chrome and Firefox than in Safari or Edge.
In REGEX and TEXT type problems with some phone settings autocorrect causes trouble.
On Android (Android 4.4.2) the tested browsers are Chrome (59.0.3071.125), Edge (45.07.2.5057) and Opera (58.2.287.53403). Like for iPhone, the problems are mainly related to the small size of the phone screen, which does not fit pictures, text and other objects properly.
In general, running Theory and Data Analysis round problems should be fine on Android browsers, but they will not look as good as on PC and some figures/plots might need zooming or use of Landscape mode to fit on screen. Observation round problems are currently showing some issues, which are being worked on. In case it is not possible to solve them, it is advisable to use PC-s for this round.
In CANVAS type problems, can’t zoom into the picture in either Portrait or Landscape mode in Chrome or Edge, but it is possible in Opera.
To see the MATCH type problems, one has to scroll down. To see all the categories you need to scroll right or use Landscape mode. In Opera, one can zoom out to see the whole problem.
ORDER type problems: it’s not possible to scroll and drag an answer at the same time.
Autocorrect isn’t a problem anywhere, unlike for iPhone.
On Android, the site worked fastest in Chrome, but was more functional in Opera.
