tourist's submissions are usually very clear. For the most recent contest, I looked at kcm1700's because I thought Gennady didn't participate (he just had a bad contest, as it turns out).

me, my code is very readable, that's something I'm proud of

I think you shouldn't read just one code and try to understand that....

It's better to read several codes and compare their algorithms...By this way not only you have a better chance to find a clear code but also you may learn about the problem more and more...Cause some programmers code some algorithms in a different way that they made it themselves and you can learn them to code better and faster maybe...

Now seriously, I think tourist and YuukaKazami write clear codes but they rarely participate in contests so when I want to look at the implementation of some problem, I usually refer to Enchom's (actually I learnt Aho-Corasick from his code :D) and I_love_Tanya_Romanova's codes, they are easily readable and usually help :)

Everybody has their own way of understanding the solution. tourist, Petr, rng_58 all write readable code with almost no micros. I usually code in Java that's why I find Petr code easily readable. He gives proper names to the variables and function, my level is not that good so I take time to understand the algorithm used. I learned using the TreeSet, dfs and bfs from him. Math you need to learn from your own. Apart from that I usually refer rng_58. Btw it matters most if you understand someones code and try to solve related problem like that one without using other codes.

I usually try to write nice code. Check :)
