ABSTRACT
Metaheuristic optimization is extensively used in electrical and industrial engineering, where nonlinear, nonconvex,
mixed-variable, and simulation-based models arise in power-system operation, energy management, production
planning, scheduling, and manufacturing-system design. The rapid proliferation of newly named optimizers,
however, makes it difficult to determine whether an apparent contribution introduces a distinct search mechanism
or repackages an established algorithmic lineage. This article presents Metaheuristic Lineage Mining (MLM), a
multimodal screening framework that integrates executable equation structure, normalized source-code structure,
and empirical search dynamics. Identifier-invariant abstract-syntax motifs represent update equations, normalized
token n-grams characterize implementation structure, and trajectory fingerprints summarize convergence, diversity,
exploration, and improvement behavior. The evaluation includes 57 implementations grouped into 16 documented
variant families and 1,710 controlled runs over six continuous benchmark functions and five random seeds. Fusion
weights are selected under lineage-held-out validation, preventing algorithms from the evaluated family from
influencing model selection. Code similarity is the strongest individual channel, with a mean ROC–AUC of 0.955
and top-1 lineage retrieval of 0.930; equation similarity reaches a ROC–AUC of 0.929. Search-dynamics similarity is
weaker alone but supplies behaviorally independent corroboration. Constrained multimodal fusion yields the highest
average precision of 0.769, a mean reciprocal rank of 0.935, and clustering normalized mutual information of 0.885.
Interpretable cross-family associations, including WhaleFOA–WOA and JADE–SHADE, demonstrate the ability to
expose hybrid or ancestral relations that categorical labels omit. The framework is not a detector of misconduct; it is
an auditable engineering due-diligence tool for evaluating optimizer originality before costly application studies in
power, energy, manufacturing, logistics, and production systems.
