Glover 1986 tabu search for single-objective problems. Generic over
decision type — the user supplies a neighbor-generator closure that
produces a finite list of candidate moves from the current incumbent
(e.g. all 2-swaps for a permutation, or N Gaussian-perturbed copies of
a real vector). Each iteration picks the best non-tabu neighbor (with
an aspiration override that lets a tabu move through if it beats the
best-seen-ever incumbent) and adds the chosen move's decision to a
fixed-size FIFO tabu list.
Single-objective only. Tracks the best-seen-ever incumbent across the
run, returned as the result. Generic over the decision `D: Hash + Eq`
so the tabu list can match by full decision (simple and correct;
move-based tabu is left for users to implement themselves via a
custom decision wrapper).
