But it would be nice to have a way to convert `[1,1,1,1,1,1,1,1,1]` to a rational approximation of the golden ratio. I couldn't find anything built-in, but maybe I didn't look hard enough? kcrismanThu, 17 Jan 2019 23:02:07 -0600http://ask.sagemath.org/question/45093/Infinite graphs in sagehttp://ask.sagemath.org/question/8728/infinite-graphs-in-sage/I wonder if there is some sort of lazy evaluation in sage. Assume I want to answer a finite question about some infinite structure that can be represented using finite data. As a contrived example: Consider the graph that has as its vertices the natural numbers and an edge (i,j) whenever i divides j. Is there an elegant (lazy evaluation) way to represent this? For instance I could think of a function that investigates the sizes of connected components below the first 500 primes or such.ThomasTue, 21 Feb 2012 02:46:11 -0600http://ask.sagemath.org/question/8728/
