Addressing the problem of two-dimensional steady-state thermal boundary recognition. a hybrid algorithm of conjugate gradient method and social particle swarm optimization (CGM-SPSO) algorithm is proposed. The global search ability of particle swarm optimization algorithm and local search ability of gradient algorithm are effectively combined. which overcomes the shortcoming that the ... https://www.jmannino.com/flash-grab-German-WW1-Helmet-Decal-Specialized-Machine-Gunners-Regiment-top-mega/
