Both first-order and second-order cofactors can be obtained by finding all the directed trees in the augmeuted diagraph, and then, the need of computing the directed 2-trees for the second-order cofactors is eliminated. The method proposed here is particularly applicable to computer-programming. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=1319827C0C74AAE8D654BEA21B7F54D3&jid=EFC0377B03BD8D0EF4BBB548AC5F739A&aid=8F310DC8B0D0BAE1&yid=74E41645C164CD61&vid=DF92D298D3FF1E6E&iid=38B194292C032A66&sid=F1A8654ADB4E656E&eid=3E0812ED84A7B31D&journal_id=1009-5896&journal_name=电子与信息学报&referenced_num=0&reference_num=6
