graph

问题 I am using the R programming language and the "igraph" library. Suppose I have some data and I make this into a undirected graph and perform community detection (graph clustering) # undirected graph library(igraph) my_data <- data.frame( "node_a" = c("Store_A", "Store_A", "Store_A", "Store_B", "Store_B", "Store_C", "Store_C", "Store_C", "Store_C", "Store_C", "Store_B", "Store_C", "customer_4", "customer_9", "customer_1"), "node_b" = c("customer_1", "customer_2", "customer_3", "customer_3",

问题 I want to create a map with some nodes. Adding nodes works great but setting the background image does not. The docs don't describe, how to add something besides nodes and edges. Then I tried to add the map as a background image of a node like [this]( https://codesandbox.io/s/thirsty-hamilton-wqyvn) This solution has some problems: The edge is under the node. The docs say, that edges will be always under nodes. Z-index don't resolve the problem. The map node has a border which I don't need.

问题 I'm fairly new to Javascript and I'm trying to create a simple bar chart with d3.js using some data saved in the localStorage. The data in the localStorage is acquired by the following function: function logScore() { var name = prompt("Please enter your name to add to the high scores list:"); var score = game.count; var gameDate = today; var scoreObj = { name: name, score: score, date: gameDate }; scoresArray.push(scoreObj); window.localStorage.setItem('scoresRecord', JSON.stringify

问题 I'm using Microsoft.Graph to create an Office365 calendar event. It works fine and I can create an event but I need to add a couple of extra string properties to an event, so I've created an extension for that. It compiles fine. But when I try to run it and create an event with added extension, it throws an error: Code: RequestBodyRead Message: The property 'extensionName' does not exist on type 'Microsoft.OutlookServices.Extension'. Make sure to only use property names that are defined by

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: Algorithm: for G = (V,E), how to determine if the set of edges(e belong to E) is a valid cut set of a graph A subset S, of edges of a graph G = (V,E), how can one check whether it is a valid cut-set of the graph or not? Note: A cut is a partition of the vertices of a graph into two disjoint subsets. So, cut-set of the cut is the set of edges whose end points are in different subsets of the partition. I am

问题 I am trying to create valued bipartite projection from my data which looks like the following: Name rid Emile 17560 Lou 11800 Luther 11800 Tot 11800 Phineas 11800 Phineas 13580 Calvin 13580 Calvin 11800 Les 11800 Jeff 11800 Sonny 13580 Leon 13580 Red 13580 I imported the above data and call it data1 Then I do the following: ##create graph object from data1 graph1 <- graph.data.frame(data1) #check if it is bipartite is.bipartite(graph1) FALSE ##convert to bipartite graph V(graph1)$type <- V

问题 I know this is usually done with breadth first, but we are asked to do it with both, I already accomplished breadth first.... I feel like this is a pretty typical example of using a depth first search, so I was hoping I could get some help here... I am attempting to find the shortest path through a maze using depth first search, but as of right now I cannot wrap my head around how exactly to do it. This is my code so far: void maze::findPathRecursive(graph &g, int position, int goal) { if

问题 My last question was closed because apparently is a duplicate and had been responded several times. However, none of the answers mentioned (Unable to show a Git tree in terminal, Pretty git branch graphs, Visualizing branch topology in Git) resolves my question. Among those there is a very complete answer, but is for git on Linux; there are many others that give complex commands, but they do not show what I'd like to see; and there are others referring tools to paint a contrived topology (not

问题 I am currently porting code for a service from using SMTP to Office 365. With SMTP I am able to set different user names on a mail from shared inbox using the "from" field, while retaining the shared email box address. This does not appear to be working via Office 365. The process flow is: Customer fills in a web form that is sent to the shared email box The service reads the email, allocates a user to this inquiry and sends a confirmation email back to the customer from the shared box but

问题 I have cars,cities and routes. Every city is a node. Every route is a path generated by a car. Different cars will have different path, sometimes paths could be intersected (which means differents cars have found the same city in they path), sometimes not. I would rappresent a graph with all the cities and all the different path and plot the graph with plotly. Example: List of cities: CityA -CityB -CityD -CityZ -CityK List of cars: Car1, Car2 Routes: Car1 will have a path through cityA -
