Hi, I'm in the process of installing graph-tool for python via homebrew, and when I run the configure file for graph-tool (after first following all the directions here, https://gist.github.com/openp2pdesign/8864593 <https://gist.github.com/openp2pdesign/8864593> ), I get this error: checking whether the Boost::Graph library is available... no configure: error: No usable boost::graph found Does anyone know how to resolve this?

Drawing on screen
by Hang Mang 10 Mar '14

10 Mar '14

As I understood I can simply call graph_tools.draw.graph_draw(g) and it should get drawn on a screen. But I get this error when I don't specify the 'output' parameter (i.e just call the function with the graph object). Error: Couldn't recognize the image file format for file '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/draw/graph-tool-logo.svg

How to implement graph version of map/reduce
by cammil 10 Mar '14

10 Mar '14

Is there a way to implement an arbitrary walking and/or reduction of a graph? I feel this is analogous to map/reduce for lists/iterables. This is my first foray into implementing graphs in software, and I'm not sure whether this is possible, desired or already existing in graph-tool implementation. I feel this type of functionality is essential if I am to use graph-tool for my experimentations. I am thinking something like: A function called "graph_walk" (which is analogous to map) which takes a "walk method" and a mapping function. The "walk method" might have several different parameters: e.g. revisit nodes allowed - Boolean maximum nodes to visit - +int minimum nodes to visit - +int spawn new walkers - function of the node/edge which returns boolean algorithm - breadth first / depth first / ... randomisation - function returning probability of walking down edge from node (defaults to function returning 1) -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com… Sent from the Main discussion list for the graph-tool project mailing list archive at Nabble.com.

Hi, Any plans on supporting visualization of temporal dynamics? Or is there any way of doing that with the current feature set? Regards, Håkan
