Background:

Omics technologies offer potential for new biomarker discovery.
Clinical translation of omics-derived biomarkers is limited.
Effective feature selection is critical for robust and translatable biomarker panels.

Purpose of the Study:

Introduce GARBO, a novel multi-island adaptive genetic algorithm.
Simultaneously optimize classification accuracy and biomarker set size for omics data.
Address challenges in clinical translatability of omics-driven biomarkers.

Main Methods:

Developed GARBO, a multi-island adaptive genetic algorithm.
Tested GARBO against six alternative feature selection methods.
Evaluated models using Pareto-based selection and weighted sum strategies.

Main Results:

GARBO identified biomarker sets optimizing accuracy and minimizing feature count.
Applied to cancer patient stratification and drug sensitivity prediction using diverse omics data.
Demonstrated superior performance over existing methods in identifying accurate and concise biomarker panels, confirmed on independent datasets.

Conclusions:

GARBO effectively balances biomarker accuracy and set size.
Facilitates the development of cost-effective and clinically translatable biomarker panels.
Offers a robust approach for omics-driven biomarker discovery in precision medicine.
