The probability of the opposite step is the product of

- 1.
- probability to pick particle 2, and the displacement vector , equal to , and
- 2.
- probability to accept the move by the Metropolis criterium

If the state 1 has higher energy than 2, then , and , the first contributions are the same in both direct and reverse probabilities, and equation 2 is satisfied.
