这是我最近看到的一篇论文,思路还是很清晰的,就是改进的LPA算法.改进的地方在两个方面: (1)结合K-shell算法计算量了节点重重要度NI(node importance),标签更新顺序则按照NI由大到小的顺序更新 得到ks值后,载计算一下节点邻居ks值和度值d的比值 (2)当出现次数最多的标签不止一个时,再计算一下标签重要度LI(label importance) 其实就是找到节点相同标签的那些令居计算一个合值,看着也不难啊 (3)最后这个算法使用的是异步传播 下面是我实现的代码 func…

在过去的几个星期里,我开始看到基于 CSS Grid 的布局框架和栅格系统的出现.我们惊讶它为什么出现的这么晚.但除了使用 CSS Grid 栅格化布局,我至今还没有看到任何框架能提供其他有价值的东西.他们沉醉于模仿过去的做法,而不是着眼于未来.这使得发展受到限制.其中一个常见的问题就是,这些框架仍需要在标记语言中使用行包装器. 为什么 Grid 有些不同? Grid 是一个栅格系统.它允许你在 CSS 中定义列和行,而不需要在标记语言中定义它们.你不需要其他工具帮助你实现一个看起来像栅格的效果…

当我们要把一个地块导出为txt的时候,应该怎么写,这是比较有用的这样可以帮助我们存档之类的,这里是基于某个地方的独立坐标系,是基于自己发布地图,如果是用百度地图或者其他网上的地图可能不适用. package com.szpl.extension.util { import com.esri.ags.geometry.MapPoint; import com.esri.ags.geometry.Polygon; import com.esri.ags.layers.GraphicsLayer; i…
