Ni–TiC composite coatings were prepared on substrate of aluminum alloy by pulse electrodeposition. The plating parameters for optimizing wear and corrosion resistance of Ni–TiC composite coatings were selected by orthogonal test, including the TiC particles concentration, current density, duty cycle, frequency and stirring rate. A three-layer back propagation (BP) artificial neural network with Lavenberg–Marquardt...
To solve the problem of slow convergence speed of the standard genetic algorithm (SGA), the strategy of adaptively changing the search area is used to reduce the search area progressively in this paper. The tactics of concerted evolution among multiple populations is proposed aimed at the deficiency of easily plunging into a local optimal solution of SGA. Distant hybridization strategy and a new method...
