How much does a quantum oracle to find a needle in a haystack really cost?
@skeptic: I don't understand. By assumption (this is part of the question), $f$ is a map that accepts database entries (binary strings) as input and outputs 0 or 1. $f(x)$ is 1 if and only if $x = w$, where $w$ is the string we are looking for. |

Can you maximize the spectral norm of a matrix in a semidefinite program?
Right, that makes sense. Thanks. |

Can you maximize the spectral norm of a matrix in a semidefinite program?
Thanks. But does that rule out the possibility that introducing new variables and changing variables will make it an SDP? For example, geometric programming (en.wikipedia.org/wiki/Geometric_programming) is in general non-convex, but a change of variables makes it convex. |

Can i achieve something better with the probabilistic turing machine in matter of space?
Are you asking if a non-deterministic machine with space f(n) can solve the same problems as a one-sided error randomized machine with space f(n)? |

Is P=NP relevant to finding proofs of everyday mathematical propositions?
A very interesting observation: "people might like my proof better than the lexicographically first one" |

Hamiltonicity is so very monotone. |
