摘 要：

In this talk, we will present an efficient framework algorithm for interface related optimization problems, where the interface is implicitly represented by indicator functions. Based on the indicator function representation, we construct a concave approximation and relaxation to the original problem and develop an unconditional stable algorithm.  Many applications including image segmentation, fluid flow optimization, flow network formation, and heat sink design will be discussed.
