Welded beam design method based on hybrid differential artificial bee colony algorithm

The invention discloses a welded beam design method based on a hybrid differential artificial bee colony algorithm. The method comprises the following process of generating a candidate solution obeying Gaussian distribution through fusion of a triangular search strategy and a hybrid differential enhanced Gaussian bare-bones artificial bee colony algorithm (EABC-BB), thereby preventing the algorithm from running into a local optimal solution while not reducing the exploration capability of the algorithm and being beneficial to inhibiting premature convergence of the algorithm; in the EABC-BB algorithm, in order to enhance the capability of the algorithm to adapt and solve different problems, dynamically adjusting a crossover probability according to successful search experience of the previous generation; converting a welded beam design problem into an unconstrained optimization problem by use of a penalty function method; and finally, solving the unconstrained optimization problem converted by the welded beam
