Feb 3, 2014 at 5:02 | comment | added | vzn | oh MAT cites Schaefer dichotomy thm / wikipedia. so more specifically, are there any other thms that are known to be similar to that one? | |

Feb 1, 2014 at 18:08 | comment | added | vzn | this question seems to allude to a "dichotomy thm" analog possibly from somewhere else; are there any examples of other "dichotomy thms" along these lines in the literature? | |

Jan 30, 2014 at 12:28 | comment | added | David Richerby | Your edit seems to be restricting to properties that are already in NP. Also you don't need to exclude problems that have either a finite number of "yes" instances or a finite number of "no" instances because any such problem is trivially in P so could not be a counterexample to your proposed dichotomy. | |

Jan 30, 2014 at 3:15 | comment | added | Mohammad Al-Turkistany | @JoshuaGrochow Thanks for your comment. I hope that the four examples I gave would provide "working" definition of natural interesting property of cubic graphs. Personally, I conjecture that deciding any natural interesting property of cubic graphs is $NP$-complete. | |
Jan 30, 2014 at 3:04 | comment | added | Joshua Grochow | Interesting question! But in order to get a dichotomy theorem I think one would have to pick a defn of "natural interesting property." Maybe isomorphism-invariant is enough (all your examples are, and I would think all natural examples ought to be), despite the fact that surely some iso-invariant properties might not seem "natural." A P/NP-hard dichotomy for iso-invariant properties of cubic graphs would be a very interesting theorem. (I say NP-hard and not NPC b/c one can probably cook up an iso-invariant property that is, e.g., PSPACE-complete by considering some game on the graph.) | |

Jan 29, 2014 at 22:44 | comment | added | Mohammad Al-Turkistany | Although the following does not answer the above question, I am interested in polynomial-time decidable natural interesting properties of cubic graphs. If no such examples exist, It is natural to conjecture that deciding any natural interesting property of cubic graphs is $NP$-complete. | |
