英文摘要	The derivative-free trust-region algorithm proposed by Conn et al. (SIAM J Optim 20:387-415, 2009) is adapted to the problem of minimizing a composite function Phi(x) = f (x)+ h(c(x)), where f and c are smooth, and h is convex but may be nonsmooth. Under certain conditions, global convergence and a function-evaluation complexity bound are proved. The complexity result is specialized to the case when the derivative-free algorithm is applied to solve equality-constrained problems. Preliminary numerical results with minimax problems are also reported.
