Module metaheuristic 

Swarm-intelligence and nature-inspired metaheuristics.

Each algorithm implements the Strategy trait over tensor-backed populations so it plugs into the same EvolutionaryHarness pipeline as the classical families (GA, ES, DE, EP, CGP).

firefly	Firefly Algorithm	Real	Useful for multimodal
bat	Bat Algorithm	Real	Legacy comparator
salp	Salp Swarm Algorithm	Real	Legacy comparator
aco_perm	Ant Colony (permutation)	Permutation	Stub — deferred to a future release

Calibration

Not every algorithm in this module is competitive on serious benchmarks. Several (GWO, WOA, BA, SSA) are flagged as “legacy comparator” in their module docs, per Camacho Villalón et al. (2020) and Sörensen (2015). The library ships them because they are widely cited; users asking “which one should I pick?” should start with pso and move to CMA-ES or LSHADE once those land.

See README.md in this module’s source directory for the full calibration table and prose guidance.

Custom kernels

The kernels submodule ships fused CubeCL kernels for two operator paths where the pure-tensor decomposition is measurably wasteful: the pairwise-attract inner loop used by firefly and the Lévy-flight sampling used by cuckoo (and optionally bat). The kernels are gated behind the crate-level custom-kernels feature; pure-tensor fallbacks always compile.
