execute

open override fun execute(candidate: BinarySolution): BinarySolution

Executes a single-bit flip on the candidate solution with probability probability.

Implementation notes:

Assumes candidate is a BestSubsetSolution (cast is unchecked and will throw if not).
Chooses a random index in [0, n) and toggles the bit.
Resets incremental evaluation state and mutation flags, since this is not a fixed‑K swap.
