[sage-support] Approximating real roots of cubic equation
Hello, I opened a ticket Wrong approximate real roots of cubic equation and matrix eigenvalues #412 because frustrating me too much :-) (joking) Is it ok or am i math foolish ? Maybe there are two tickets in one : one for Maxima (behind the scene solver) and one for Sage (converting argument calls). I have seen similar problems on other geometric computations involving equations solving ... but in my special case of geometric worksheet (intersection of conics) it is a core problem, because trying to get a degenerate conic...I need to have sometimes EXACT roots of cubics and sometimes APPROXIMATE but "pure real" root finding is a necessary condition for my computations. Dominique. PS : I am not in hurry ... I will code a cubic equation solver myself (for symmetric matrix/equations). -- You received this message because you are subscribed to the Google Groups "sage-support" group.

If performance is a problem you may want to work a bit more on the exploration algorithm, but if you do so do not overestimate what speed you could gain this way: there is no magical way to compute a TSP, and no magical way to get them all either. Just be careful when using the subgraph_search_iterator() function, as you will get every cycle on 'n' vertices for a total of 2n times.

Thanks, but without knowing how this is obtained, it is not useful, sorry.

there is subgraph_search_iterator() which might not be optimized for cycles too much, but does the job, I guess: sage: p=graphs.HeawoodGraph(); p Heawood graph: Graph on 14 vertices sage: c=graphs.CycleGraph(14); c Cycle graph: Graph on 14 vertices sage: len(list(p.subgraph_search_iterator(c))) 672 On Saturday, February 6, 2016 at 7:16:31 AM UTC, Christian Stump wrote: > > Hi there, > > is the functionality to get *ALL* hamiltonian cycles in a graph somehow > already available in Sage?
