Will there be a solution pdf published?

I'm sure the solutions will be posted a bit later on a contest page. Meanwhile you can get it from here: https://drive.google.com/open?id=1-WA0Yld3B-L_d-CzrC-nBNj13kdc0eiw

Great puzzles and a lot of new ideas!
Is there a way to see the puzzles from the aforementioned Moscow Cup ?

Isn’t this a valid solution for Incorrect Products too?

Para: The 6 is replaced by a 18; that's not a change of one digit.

And to the puzzle: It's a shame to know that Unknown Diginet has multiple solutions. That must be why I was wondering how you can possibly approach this logically.

Ah, okay. I didn’t really read the rules carefully enough. I just went with, they all work the same as the first, which was one incorrect clue.

For beta, also the line has to turn at each dot? Otherwise the example seems not unique.

The alpha rules are nice, unfortunately some Slalom-like rules were too promising for me (no loops, then no crosses: seemed to work fine for the example and the first puzzle, but the second one is contradictory quite late).

You're right, it should also make a turn at each dot!

Example is not unique for slalom-like solution, there's one cell that may contain either slash.

Thank you for the solutions, Vladimir. I solved Gamma as "Path must alternate going through circle-wall-circle-wall..." but did not realize the additional constraint. It solved the example uniquely but obviously not uniquely for the puzzles themselves. Which might explain why I had to guess and was happy (at the time!) to reach a conclusion! :)

I thought it was a great contest. I did have one question about the incorrect products puzzle. I got an answer of 45213 and 23541 doing this the 36 was the incorrect product. Maybe I am missing something but after checking many times this seems to be a possible alternative solution.

The rules say there's just one incorrect digit. If you have a solution with 36 turning into, say, 16 or 35, please share, but I still think the solution is unique.
