nodes

问题 I just want to set a node to sleep in ns-2 and i have searched in protocols and i found a lot of objects and functions about sleep but i couldn't use them in other protocols to set a node to sleep. when i use them i get Segmentation fault or Floating point and i know what these errors mean but i can't find a way to solve them. Like when i use sleep() function from SMAC. I have searched in google and after a week i still didn't find any solution...! could you guys please help me here...? 回答1:

问题 If I have a node class(es) that can accept a generic type for it's key value: class Node<K extends Comparable<K>> implements Comparable<Node<K> { ... } class KeyValueNode<K extends Comparable<K>, V> extends Node<K> { ... } Is it possible to declare a generic binary tree class that accepts a generic type of node, which can contain a generic type of key value? I thought it would look something like this.... class BinaryTree<N<K>> { N<K> root; BinaryTree<N<K>> left, right; ... } Apologies for

问题 I have a program that reads a file with two columns of numbers, sorts them, creates three tables, one with only the nodes (individually), one with all the edges and one that has the amount of edges for every node. The problem is that when I try to print the edges, it prints them wrong or it says it cannot find them. Through some gdb I found out that the first arrays are fine but the third stores a bunch of random numbers (or zeros) through the end. Any help would be appreciated. The file

问题 I'm new to using NetworkX library with Python. Let's say that I import a Pajek-formatted file: import networkx as nx G=nx.read_pajek("pajek_network_file.net") G=nx.Graph(G) The contents of my file are (In Pajek, nodes are called "Vertices"): *Network *Vertices 6 123 Author1 456 Author2 789 Author3 111 Author4 222 Author5 333 Author6 *Edges 123 333 333 789 789 222 222 111 111 456 Now, I want to calculate all the shortest path lengths between the nodes in my network, and I'm using this function

问题 I'm not sure if I'm doing this correctly as this is my very first time coding with nodes. But here's my code so far, if someone can look over it and help me out with understanding if I'm doing anything wrong. Also my insert/remove methods are giving me a hard time. The professor gave us the pseudocode for that but I can't seem to grasp how to interpret it into Java code as I've never done this type of code before. Mostly because there's a if statement that checks the heights to see if the

问题 I have several thousand gene trees that I am trying to ready for analysis with codeml. The tree below is a typical example. What I want to do is automate the collapsing of tips or nodes that appear to be duplicates. For instance, descendants of node 56 are tips 26, 27, 28 etc all the way to 36. Now all of these other than tip 26 appear to be duplicates. How can I collapse them all into a single tip, leaving just tips 28 and one representative of the other tips as the descendants of node 56? I

问题 I am struggling to find a way to remove this node: <Mapping Key="pdf" Value="icpdf.gif"/> I have listed the XML file at the bottom of this thread. This is what I've got so far. This is what I'm running: $xmlFile = “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\XML\docicon.xml” $xmlDoc = [XML](gc $xmlFile) $xml =[xml]'<DocIcons><ByExtension><Mapping Key ="pdf" Value = "icpdf"/></ByExtension></DocIcons>' $xml | Select-Xml -XPath '//Mapping' | ForEach-Object{$_

问题 I am relatively new to networkx and plotting using matplotlib.pyplot and would like to know how to modify the color (or other attributes such as weight) of a node's outline. By "outline" I don't mean an arc or edge between two nodes; I mean the thin black line around the circle that is by default used to represent a node when plotting a network. So for example, when I make a graph that has just a single node and display it: from networkx import * import matplotlib.pyplot as plt plt.ion() G =
