I think, a contest would be something that should be run when the mainnet is live for quite a while and proves to be stable. This would be the only time to collect XEL anyway and I'd much prefer people having the time to adjust to XEL and try it out before the contest is run, as opposed to starting the contest, basically the very second XEL goes live.
The travelling salesman problem may be a poor example. And you are right, that it is the network solving the problem, so you as a job author may just be extremely lucky or unlucky. Maybe a kind of Olympiad may be a solution, where there are multiple tasks to solve?
I am definitely not the right person to come up with specific tasks. Ideally, it should be something like finding the most accurate solution for a problem, instead of being the fastest to find the right solution(in case of an Olympiad style approach, both way may be feasible, though). Additionally, it should be something, where there is no "ideal algorithm", sorting algorithms may come to mind?
Obviously, the main focus of such a contest should be on using the Elastic network as efficiently as possible. This would include, that every contestant has a publicly known account, which can be observed, as well as a fixed number of XEL.
I thought about sandboxing the whole thing, as in running it on a testnet, but this would not show off the computational strengths of the Elastic Network as a whole.
If yes, what does he_she win? BTC? XEL?
*I'm still thinking about making the Elastic Network play chess against itself. Or Go, or tic-tac-toe or whatever

Do you volunteer?
Sorry, I'm not trying to seem pressuring, since of course you are not obligated, but getting anything going requires someone specific. The workload wouldn't have to be all you alone, as others (such as Selsonblue) seem to be ready, but you being involved would lend the aid of reputation as an original contributor. (Of course, any other original contributor reading this could volunteer too or instead, but there aren't that many).

Don't mistake a loud voice for a smart voice
Seriously though, to be completely honest, I don't feel comfortable with holding large amounts of money I don't own. I would use a reputable escrow for that, especially since I am not really a known or trusted entity in this forum. I wouldn't send me money and that is what escrows are for.
If it comes to things like writing out contest rules, setting up timeframes and so on, I might find time to do something like that.
But as mentioned earlier, we would need people to actually come up with tasks for the contest. Any suggestions?
