pajek時間網(wǎng)絡使用方法

1、pajek時間網(wǎng)絡使用教程時間網(wǎng)絡(temporal network )分為兩種類型一種是 Time Events，在某個時間點發(fā)生改 變；另一種是time intervals，在某個時間段網(wǎng)絡狀態(tài)維持不變。文件后綴.tim。1 .net文件顯示時間網(wǎng)絡以lin_rel4.NET文件為例 該文件是以時間延續(xù)1.1讀文件File/Network/Read->lin_rel4.NETFile MetwortN etwvorks OperationsPartitionVMtcr VtNetworkPartin crRo-jd Timo EvbttCtrl 4 T1.2生成時間網(wǎng)絡Network

Only Differe nt-Ge nerate n etwork in specified time only if the new n etwork will differ inat least one vertex or line from the last n etwork which was gen erated.與上次網(wǎng)絡相比發(fā)生變化時生成網(wǎng)絡?
