摘要:
In the first part of this talk, we study a convex-constrained nonsmooth DC program in which the concave summand of the objective is an infimum of possibly infinitely many smooth concave functions. We propose some algorithms by using the extrapolation technique for this problem, and analyze their global convergence, sequence convergence and also iteration complexity.

In the second part we consider a class of DC constrained nonsmooth DC program. We propose a penalty method for solving this problem and show that it converges to a B-stationary point under much weaker assumptions than those impose in the literature.

This is joint work with Zhe Sun and Zirui Zhou.
