How to calculate $det(X^TX)$ efficiently, update one column of X each time
Not a good fit for this side - I suggest scicomp.stackexchange.com. Anyway: Why not do a factorization of $X_1$ (LU or QR) and down- and update that? |

Nope, not linear since flipping the sign of my won't flip the sign of the value. |

One more thing: Your functional is not linear but only positively homogeneous, so what kind of result do you expect? |

What form of Sobolev norm are you using, i. e. how are the sup-norm of the function and it's derivative combined? |

Projecting a convex partition onto a convex set
$X$ could be empty or have $n-1$ points... You need some more conditions. |

Which way for reading the proofs?
@fanzheng I heard a similar quote about a famous optimizer "I don't read papers, I write them." |
