A shortest sequence of reversals sorting a permutation is called an optimal sorting sequence.

The score of a sequence of reversals is still given by the sum of the scores of its reversals.

The length of such a sequence of reversals is called reversal distance, denoted by d π, π d ) (or simply d, when π d = ι n ).

The traditional SPSR algorithms for the HP model however output just one optimal sequence of reversals, while the space of optimal solutions can be huge.

The score of a sequence of reversals is bounded by k, that is, each sorting sequence in a near-perfect trace has at most k breaking reversals.
