Maximum Series-Parallel Subgraph, given a connected graph ., outputs a spanning tree of ., is a .-approximation. Indeed, if . is the number of vertices in ., any spanning tree in . has .−1 edges and any series-parallel graph on . vertices has at most 2.−3 edges. We present a .-approximation for this problem and results showing the limits of our approach.defibrillator 发表于 2025-3-24 00:35:07

Dingfang Chen,Mei Yu,Grizelle González,Qiong Gaoeing organic compounds which are translocated in the symplast (see reviews by Brabec 1965 and Carr 1976). Although symplastic continuity between cells in the graft interface has often been postulated, reliable experimental proof was difficult to obtain because of the uncertainty in localizing the exPATHY 发表于 2025-3-24 17:43:48
