Abstract In this paper. a curve approximation approach using bio-inspired polar coordinate bald eagle search algorithm (PBES) is proposed. PBES algorithm is inspired by the spiral mechanism of bald eagle during predation. By introducing polar coordinate. https://www.roneverhart.com/Rag-Bone-Dress-Marylebone-Black-Leather-Silk-Chiffon-Size-2-Tiered-Mini-NEW/
