Zig-Zag Zig-Zag Zig-Zag
The creators of the zig-zag product win the Gödel Prize
Omer Reingold, Salil Vadhan, and Avi Wigderson won this years Gödel Prize for their brilliant work on the Zig-Zag Graph Product. I think this is a wonderful choice, and congratulate all three of them.
I am planning a post on this work in the future, but had to say something today. Especially, after my comments in an earlier post on the Gödel Prize.
I always end with an open problem. I guess today the best problem is to think of new ways to exploit their terrific ideas. I am sure that the zig-zag product will be used in many future papers.
