I think questions whose titles are like:
How I can find a recent papers on the subject of Turing machine which exhibit computational power beyond blah blah blah...
Can we have a policy (or at least some guideline) asking the poster to trim his/her question in a meaningful way?
PS: There's already a policy on the minimum length of the title (15 chars). The policy is enforced by the SE. (To clarify, I'm not after such enforcement.)
Edit: Since Tsuyoshi asked for concrete cases, here I mention several:
- Are there any models of computation currently being studied with the possibility of being more powerful than Turing Machines?. The body of the question exactly duplicates the title. I'd write a title like More Powerful Models than Turing Model.
- What happens if we try to extract a witness but it actually does not exist from a term of existential type?
- For a Planar Graph, Find the Algorithm that Constructs A Cycle Basis, with each Edge Shared by At Most 2 Cycles
- Functions which are easy/hard to optimize on a given class of graphs with vertex sets growing exponentially in the length of input
The list goes on...
