Anti-concentration of Gaussian quadratic form
Yes, I would expect $c=1/2,$ but I don't want to discourage somebody with an answer that gives $c<1/2.$ |

Anti-concentration of Gaussian quadratic form
No, it's supposed to be an absolute constant independent of $a_1,\dots,a_n$ and $n$. I will update the question. |

linear program with zeros
I guess, appropriately rephrased this could be a somewhat interesting math overflow question. Like, what algorithms/heuristics are known to solve mixed integer linear programs, which instances are easy etc. |

linear program with zeros
looks more like a quadratic program than a linear program, since you can express that a variable is either zero or one. You can't hope to solve this efficiently in general. Look for integer linear programming solvers on the web. |

Algorithm for decomposing permutations
So, the solution could have exponential length so that you can't write it out in polynomial time. Instead you release, say, a Turing machine which on input $i$ returns the permutation $g_i$. This can be done efficiently. |
