comment Using Mathematica in better way?
I don't know, man, I've never used DumpSave myself. It sure seems to me that DaveStrider's link says that's what you need to do, but what do I know? (When you say "only thing i have to write in cell" you know you also have to hit Shift+Enter to evaluate it, right?)

There is no need for a [mathematica] tag because every single question on this site is supposed to be about Mathematica. I have removed the [webmathematica] tag.

That's what I get for answering on my phone, I suppose. Fixed now :)

comment FindRoot over a domain, but give domain boundary if no root exists
Sorry, "because" should have been "when": If both endpoints have the same sign, that's when you can pick the appropriate endpoint without calling FindRoot.

Since $f$ is monotonic, you can just pick the endpoint which has the smaller absolute value of $f$. As a bonus, you can do this without needing to call FindRoot because that's just going to produce an error anyway.

It should be Filling -> 0, though.

comment Planning for the Tube Challenge using Mathematica
@alan, the trouble is that the graph may not be Hamiltonian in the first place, so there is no travelling salesman tour. If you add edges of weight Infinity to make it complete, all that happens is that now every possible tour has equal weight Infinity.

Your list doesn't specify which stations are adjacent.
