Let Nature Solves NP-Complete Problem

... for computers too. Any decent book on algorithms will give you several elegant, easy-to-implement, blazingly fast methods. The TSP, like all NP problems, is much different. Thinking about the gas-tube device (which is a really cool idea, I must say) there's no way to apply it to the TSP. Electricity just doesn't work that way.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
