Edge

I'd like to ask you if there are any algorithms how to minimize edge crossings in graph, for example if I have a transition matrix of the graph. I found methods like trying to place the nodes around the other node, but I'd like to know some other ideas. Thanks. There's a range of well established algorithms/libraries that have been developed for graph drawing applications, you can get a bit of background here . To draw undirected graphs a popular choice is the force-based layout algorithm, in which graph edges are treated as springs (attractive forces) while the vertices are treated like

According to the book (Intro to Algorithm), in dfs, edges are classified as 4 kinds: Tree Edge, if in edge (u,v), v is first discovered, then (u, v) is a tree edge. Back Edge, if ......, v is discovered already and v is an ancestor, then it's a back edge. Forward Edge, if ......, v is discovered already and v is a descendant of u, forward edge it is. Cross Edge, all edges except for the above three. My question is how can I identify whether v is u's ancestor or descendant when I'm trying to figure out if (u, v) is a back or forward edge? If you really need it, you can check it by maintaining

Redmine 是一个基于Web的灵活的项目管理（Project Management）软件。它是开源、免费、易扩充的，同时Redmine社区（ www.redmine.org ）也非常的活跃，这保证了Redmine能够更新支持更多实用的功能。但是Redmine的安装步骤比较复杂： http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_in_a_sub-URI_on_Windows_with_Apache ，而另一个社区BitNami提供了一个整合的安装包（ http://bitnami.org/stack/redmine ） ，支持Windows、Linux、Max等系统，同时BitNami提供了一个配置好Redmine的Linux下的虚拟机环境，下载即用。BitNami-Redmine安装包将会安装：Redmine、Apache、ImageMagick、MySQL、Subversion、Git、Ruby、Rails、RubyGems等软件。安装包也会安装Subversion，使用命令行可以启动svnserver和创建版本库，但为了更友好的界面和更好的管理，我们将会使用CollabNet的SubversionEdge来管理和使用Subversion。BitNami

In my app i change the overscroll glow effect color like this: int glowDrawableId = contexto.getResources().getIdentifier("overscroll_glow", "drawable", "android"); Drawable androidGlow = contexto.getResources().getDrawable(glowDrawableId); assert androidGlow != null; androidGlow.setColorFilter(getResources().getColor(R.color.MyColor), PorterDuff.Mode.SRC_ATOP); But when i updated to lollipop this code crashes. I get following error code: FATAL EXCEPTION: main Process: com.myproject.myapp, PID: 954 android.content.res.Resources$NotFoundException: Resource ID #0x0 at android.content.res

I want to give the effect that the ListView has faded from whatever is around it. By default it is set to whatever colour your ListView is. I can adjust the orientation of the FadingEdge and the size of the FadingEdge but not the colour. Is it possible? Yes you can ! setCacheColorHint(Color.WHITE); You'll need to create a new class that extends ListView. package com.mypackage; import android.content.Context; import android.util.AttributeSet; import android.widget.ListView; public class ColorFadeListView extends ListView { // fade to green by default private static int mFadeColor = 0xFF00FF00;

I want to create a depth first search which I have been somewhat successful in. Here is my code so far (Except my constructor, note the Vertex and Edge classes only contain properties, nothing important to post here): private Stack<Vertex> workerStack = new Stack<Vertex>(); private List<Vertex> vertices = new List<Vertex>(); private List<Edge> edges = new List<Edge>(); private int numberOfVertices; private int numberOfClosedVertices; private int visitNumber = 1; private void StartSearch() { // Make sure to visit all vertices while (numberOfClosedVertices < numberOfVertices && workerStack.Count
