search for: subgraphs

Dear All, I would like to seek for help on this issue: 1. I set par(mfrow=c(2,2)), hoping to plot 4 subgraphs in a whole graph 2. Each subgraph has its own x,y axes and each has x-axis label and y-axis label 3. moreover, subgraphs in the left column of the whole graph are all 3D, and have z axes and labels for z axes 4. subgraphs in the right column of the whole graph are all 2D 5. In each subgraph, x-ax...

Hello, I'm running an algorithm for graph structural cohesion that requires a depth-first search of subgraphs of a rather large network. The algorithm will necessarily be redundant in the subgraphs it recurses to, so to speed up the process I implemented a check at each subgraph to see if it's been searched already. This algorithm is very slow, and takes days to complete on a graph with about...

Estimado Javier, Me alegra que hayas avanzado con tu error. Te respondo a esto último. La función induced.subgraph() espera como segundo parámetro una lista de los IDs de los vértices, mientras que tú le estás pasando una lista de 'edges'. Prueba lo siguiente: c <- induced.subgraph(datos.network, which(V(datos.network)$name == 'Casa')) Si entendí bien todo, debería

Dear All, I would like to ask a question on how to do overlay plots in each subgraph of xyplot. 1. I did simulations for m=1000, 2500, 5000, 10000, as the sample sizes. 2. for each sample size value m, 4 graphs are generated; each graph contains overlayed comparisons between 4 methods, 3. now I want put them into a 4-by-4 plot by xyplot, i.e., 4 sample size values, each of which has 4 plots.

Hi all, I want to find all the mappings of one graph in another graph, based on their vertex labels Is there any way to do this in igraph based on vertex labels. (as far as i know Igraph allows the subgraph isomorphism based only on vertex and edge colors) Eg: graph 1: x(1) x(2) x(2) y(3) y(4) x(1) z(5) x(2) graph 2: x(1) y(2) # the brackets contain the corresponding vertex ids i would like my

I need a function that builds subgraphs up to a limited distance from an input root node. I feel like this is a common enough task that there's probably an easier way to do it, but I'm still learning what tools are available to me in igraph and built my own solution. The code below was tested on a machine that didn't have iss...

Hi R-users, I'm using igraph for an undirected graph. i used clusters() igraph function to know the component size(subgraphs) as shown bellow: c <-clusters(g)    # component sizes size <- sort(c$csize, decreasing=TRUE) cat("Top 20 cluster of the graph","\n") for (i in 1:20) {   cat(i,"  size:",size[i] ,"\n") } Can anyone help how to extract the subgraph components  based on...

...both directions to prove that ;) All that's been shown is that you can reduce it to a hard problem. You can also reduce it to 3-sat., but that doesn't mean anything unless you can reduce 3-sat to it. 5. The actual problem the outliner is trying to solve is actually more like > finding subgraphs that are isomorphic, making the problem even harder > (something like "given dags A and B does there exist a subgraph of A that > is isomorphic to a subgraph of B") > > This assumes, strongly, that this reduction is the way to do it, and also that SSA/etc imparts no structure...

Hi all, In lattice plots, is there any option to position the panel strips with text below each subgraph, instead of above? i.e. in: Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) ,is there any way to make "Depth" appear below the subgraphs, instead of above? I've been looking through the lattice documentation and the list archive but have not found such a thing.

Estimados Tengo un problema. Con igraph creo una red a partir de un data.frame, las dos primeras columnas son V y las restantes E. Hay un trabajo anterior, yo me pregunté ¿Qué pasaría si las cosas hablaran entre ellas?, entonces hay un cruce de información de todos contra todos y elimino los nulos y duplicados. Al ver los listados E, V tienen la información. Hasta ahí estaría todo bien (me

There's another issue with re-running the vectorizer (which I support, btw - I'm just saying there are more problems to solve on the way :-) ) Historically, we haven't even tried to evaluate the cost of the "constant" (not per-iteration) vectorization overhead - things like alias checks. Instead, we have hard bounds - we won't perform alias checks that are "too

Dear All, we have released version 0.6 of the igraph package today. This is a major new version, with a lot of new features, and (sadly) it is not completely compatible with code that was written for the previous igraph versions. (See "Major new features" below for details.) I have included below a list of (bigger) changes. Please see the details in the release notes and the NEWS

...ombiner, and probably a few other passes as well. Benefits would include not missing cases missed by the current combiner and also more easily adapting to changes in the LLVM IR. All previous superoptimizers have worked on linear sequences of code. It would seem much better to operate on small subgraphs of the program dependency graph. I haven't worked out the details...

Hello, I want to have an operation foo with variable number of operands, and I am trying to achieve it using multiple operations. Let's say I want to have [FOO r1, r2], I am constructing the DAG as follows : consumeArg(r1) -> consumeArg(r2) -> FOO -> arg(r1) -> arg(r2) Note that the arrows are all "Chain"s. I need to have consumeArg(r1) because, I don't want the

igraph is a package for graphs and networks. It has a C core and uses a simple and fast graph representation allowing millions of vertices and edges. NEW FEATURES: - We use the ARPACK library for graph related eigenvalue problems, like Page Rank calculation, Kleinberg's hub and authority scores, eigenvector centrality, etc. There is also a generic interface if someone wants to use

Hi, I have worked with GCC prior to using LLVM, and I am a bit startled to find no way to use an earlier operand as is done in GCC. For example, a sext instruction on my target takes one the operand of a low-part register, and then sign extends into the full register.I find that there is no way to use for example (set RC:$srsc, sext($src, 16)), or in any other way use a sext operator to perform
