In 1995, divers first noticed a group of bizarre sandy "crop circles" on the seabed around Amami Oshima Island, southwest ...

Abstract: This study presents a comprehensive mathematical model for analyzing optimum frequency hop (FH) patterns (OFHPs) derived from two-dimensional circular shifts applied to a Golomb Costas array ...

Abstract: In this paper, circular area movement optimization (CAMO), a novel global search algorithm, and its hybridization with the pattern search method (PSM) are proposed to solve the multimodal ...
