Seems very interesting! I'll review that on a cleaned history. |
moRealVectorNeighbor: neighbor type for real-valued vector solutions with delta-based forward/backward moves via moBackableNeighbor.

Add virtual finalize() and hasFinalize() to moeoAlgo/moeoPopAlgo hierarchy. NSGA-II implements finalize() to recompute fitness and diversity assignments after population modifications (e.g. immigrant integration in island model).
Replace the hasFinalize()/finalize() pattern with a moeoAlgoFinalized<MOEOT> abstract interface. Algorithms opt in by inheriting from it. Consumers check at compile time via std::is_base_of_v instead of a runtime bool.
moeoBestUnvisitedSelect: selects unvisited individuals with optional Pareto-dominance exclusion filtering. RealVectorNeighborhoodExplorer: generates random perturbation directions with geometric scaling along improving directions. Supports per-dimension epsilon and minimum scaling factors. moeoUnifiedDominanceBasedLSReal: archive-based dominance local search for real-valued multi-objective problems.

Summary
Add local search components for real-valued multi-objective optimisation,
enabling hybrid evolutionary + local search strategies.
moeo/src/selection/moeoBestUnvisitedSelect.h— selection operatorthat picks unvisited individuals, with optional Pareto-dominance exclusion
filtering.
moeo/src/explorer/moeoRealVectorNeighborhoodExplorer.h— neighborhoodexplorer for continuous decision spaces with geometric scaling along
improving directions.
moeo/src/algo/moeoUnifiedDominanceBasedLS_Real.h— archive-baseddominance local search algorithm combining the above components.
moeo/src/moeo— includes for the three new headers.Dependencies
