I'm searching for relative (after 2000) new papers about TSP.
All the papers I have found were quite hard and needed high level
mathematical skills. I'm looking for papers that are simple to read
for someone who has simple college mathematic knowledge and good
programming knowledge in Java and C (I didn't find any current paper
implementing TSP with these languages).

Any hints will be highly appreciated.

(edit)

What Im trying to say is that im searching for papers that dont need to understand
difficult formulas. For instance some papers describe algorithms, or the philosophy 
of solution. It isnt necessary to implement that algorithm, just describe the techniques.
Maybe using some simple geometry ...

I found some papers based on Lin-Kernighan methods, which seemed ok ...
