comment Eigenvalue of the adiabatic Hamiltonian of Farhi's three qubit 2-SAT problem
Jeffrey Goldstone replied to my email. He suggested to use an $8 \times 8$ Hadamard matrix as $H_B$. For $H_P$ he suggested to use the projector $I - |ground-state-of-H-imply><ground-state-of-H-imply| - |ground-state-of-H-disagree><ground-state-of-H-disagree| - |ground-state-of-H-agree><ground-state-of-H-agree|$. I am going to fix accordingly.

comment Confusion about a lemma on the time constraint of an adiabatic evolution (arXiv:quant-ph/0604077)
The author replied as follows: To be frank, both of the two interpretations are inaccurate. The proofs are exactly for the cases listed only, and do not work for any other situation. Besides, I think the complexity to make a statement for a case as general as your first interpretation is probably NP-hard.
