What is the logic in the problem numbering

[henk_stobbe]

I received in the mail:

problem 902, number 443 and after that number 166

Is there a reason or logic behind this numbering?

It's a simple incrementation. You just need to keep in mind that once a problem is created it's ID is persisted. If the problem reoccurs, it has the same ID.
