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.roneverhart.com/Doorking-2334-080-VoIP-RS-232-Control-Box-for-1830-Series/
