So, I set export SAGE_CHECK=no but the same checks went into play and failed. Then I unset SAGE_CHECK variable and the build goes through. I still have to do make test. I don't know why the checks don't work for package python, but if I could make a suggestion maybe it would be better that the

thnx for your answers. I'm dealing with an undirectred graph. In the beginning I have a given number of vertices (53 in my case now) and a list or relations between them. All I do is adding a new edge (a - b) if a is in relatoin to be. My problem is, i dont know form the beginning if it's

Sorry, I didn't get the beginning of the thread, but if you need the graph without loops, it is a tree. So, you can compute a maximal spanning tree of the graph, and see if you get the whole graph together. This will also tell you what edges to remove, if the graph is not a tree. Of course, the

Oh, I was imprecise. If it has no loops, it is a forest. So you have to get a spanning tree for each component. On Sat, Feb 5, 2011 at 10:01 AM, Luiz Felipe Martins luizfelipe.mart...@gmail.com wrote: Sorry, I didn't get the beginning of the thread, but if you need the graph without loops, it

Again... Look at diff code by differentiate??, You read at the end of the file that sage call derivative. Search in x.derivative?? , there is a methode x._derivative?? I feel that only sage manages the rewrite rules in diff. Now browse into taylor?? source, and you see that sage call the

Now browse into taylor?? source, and you see that sage call the taylor function in maxima. The taylor function in maxima seems very long to follow in ...maxima.../src/hayat.lisp. More to the point, Maxima doesn't know about any 'special' things you define like that. Our basic
