Good point. This is key, as you say. Meta-heuristics have the flexibility of providing good performance on all Combinatorial Optimisation Problems. But meta-heuristics, can also be given domain knowledge. and/or be combined with a a heuristic. E.g. Ant Colony Optimisation techniques for Travelling Salesman Problems that combines ACO with Local Search.
