The Email challenge (#21) appears to be broken again. No mail is being received. Tried with multiple mail services to no avail.

12 May - 11:47 am

Working again now.

10 May - 4:05 pm

Hello, sorry for the late answer, in fact yes there is an issue with the mail, we will try to fix it quickly. Thanks for reporting

7 May - 6:07 pm

Hi there is a issue for the challenfe Email (number 21). I don't receive a mail on any of them: gmail, hotmail, yahoo. do i fail or is it the challenge ?

28 Feb - 10:35 am

Yes we fixed it

27 Feb - 10:00 pm

Thank you, just validated contest22. The solution checker seems to have been fixed.

27 Feb - 8:40 am

Yes several solutions are accepted of course. I will check one of your answers

26 Feb - 7:51 pm

No 500 error, but the solutions I'm submitting can be verified to be correct. It can't be that only one configuration is accepted, right? - as there are multiple correct configurations for each problem.

26 Feb - 5:54 pm

contest 22 is not concerned by the issue I found, and seems to be working (I suppose you don't have 500 error on this one ?). Your solutions are indeed rejected, but I did not check them yet

26 Feb - 3:25 pm

The validation for contest 22 also seems to be wrong (it's not accepting solutions that are clearly correct). I submitted bug report yesterday.

Website issue - 29/10/2018
It was recently impossible to validate any challenge on µContest (again). We fixed the issue and it should not happen again. Have fun

Challenge disabled
It appears that some modification done by our server host has broken Multiplication of two (big) numbers (40). It will be disabled until repair. Thanks to Setsuna for notifying us ;)

Points attribution strategy - 09/11/2014
The points attribution strategy has been modified.
Here is the new attribution law : law
Moreover, from now on, the age of the challenge is taken into account. If the chall is too young, our initial estimation prevails. After 6 months, only the attribution law prevails.
