Improved Lyrebird Optimization Algorithm (Improved LOA)

Improved Lyrebird Optimization Algorithm with mimicry and territory protection mechanisms

This paper provides an Improved Lyrebird Optimization Algorithm (Improved LOA) to address these issues. The Improved LOA improves on the standard Lyrebird Optimization Algorithm (LOA) by incorporating two biologically inspired mechanisms: the mimicry mechanism, which boosts exploitation by allowing agents to recall and refine previously successful positions, and the territory protection mechanism, which encourages exploration by repelling agents from densely populated areas. These processes enhance convergence speed, solution variety, and robustness.
