Hi karbor guys: Yesterday, I had discussed this question with other guys on the weekly meeting. Maybe I have not described the question clearly. Today, I discussed with chenying and reached an agreement with him. I update the question again in the attached file and hope for the ideas from you. Please, take a look at it. Thanks very much! zengchen At 2016-10-11 09:06:33, "zengchen" <chenzeng765 at 163.com> wrote: Hi karbor guys: I have some questions about algorithm of building resource graph.
