六月ゝ 毕业季﹏ 提交于 2019-11-26 23:59:37

User ===== Id Name etc... UserFriend =========== UserId FriendId IsMutual IsBlocked 回答1: UserRelationship ==== RelatingUserID RelatedUserID Type[friend, block, etc] Agree that mutuality doesn't belong as a column; breaks normalization. 回答2: To go one record per two users and avoid consuming extra memory that the

NetLogo Efficient way to create fixed number of links

荒凉一梦 提交于 2019-11-26 21:55:03
问题 I have about 5000 agents (people) in my model. I want to give them an arbitrary number of friends and have reciprocal but random pairing. So if person A chooses person B then person B also chooses person A. My code works fine, but is fairly slow. I will likely want to increase both the number of friends and the number of people in the future. Any quicker suggestions? ask people [ let new-links friends - count my-links if new-links > 0 [ let candidates other people with [ count my-links <

荒凉一梦 提交于 2019-11-26 15:34:10

Problems/challenges involved are: Different types of activities (posting, commenting ..) Different types of objects (post, comment, photo ..) 1-n users involved in different roles ("User x replied to User y's comment on User's Z post") Different views of the same activity item ("you commented .." vs. "your friend x commented" vs. "user x commented .." => 3 representations of a "comment" activity) .. and some more, especially if you take it to a high
