WebFeb 1, 2024 · Hence a more efficient convexification based on penalty convex–concave procedure (PCCP) [28] is introduced in this paper. PCCP relaxes the Weymouth equation with a slack variable, and continuously tightens the relaxed domain to convergence through an iterative penalty on the slack variable. Then the nonconvex RM-PGF is processed into … WebApr 2, 2024 · So here convex-concave procedure (CCP) is presented for finding a local optimum to solve convex-optimization problems. Assuming that all of the and are differentiable for the ease of notation. The basic CCP algorithm has the form of gradient desent algorithm with convexify. The procedure is choosing an initial feasible point …
WebThe convex-concave procedure (CCP) [YR03] is another heuristic algorithm for nding a local optimum of (1), which leverages our ability to e ciently solve convex optimization problems. In its basic form, it replaces concave terms with a convex upper bound, and then solves the resulting convex problem, which is a restriction of the original DC ...
