I have two lists that I want to join on a condition. Unlike in a relational algebra join, if more than one element of each list can be matched, only one should be selected, and shouldn’t then be reused. Also, if any of the elements of the first list don’t match any of the secondRead more

Let $ G=(V,A)$ be a simple directed acyclic graph. Two vertices is called dependent if there is a directed path between them. Find directed paths $ \{P_1,\ldots,P_m\}$ of minimum $ m$ such that any pair of dependent vertices belongs to at least one path $ P_i$ for some $ i$ . I have no ideaRead more

Hey all, Hope everyone's just dandy! I've been working on my new eCommerce site for a few months now (it was supposed to be a 2 week job). While everything is just fine for me now, after a manic few weeks of chopping and changing themes, I'm still not getting a great response. I've madeRead more

I’m writing a program to check whether a pair of Strings (entered by the user) are anagrams or not. I’ve already did with the standard way to sort both of the strings using Arrays.sort() but I also thought of an alternative version not requiring any sorting and ended up with this: import java.util.Scanner; public classRead more

Some time ago I asked the following question on how to calculate the radial distribution function. I have here an add-on question, but before asking it I try to summarize and visualize my problem. As input I have an image where particles are seen as bright dots: After determining the positions of all particles, byRead more

Let $ S,T$ be abstract simplicial complexes. Is there a (unique) abstract simplicial complex that gives me the most of what is in common with $ S$ and $ T$ ? I’m thinking of this as an “intersection,” or “refinement” of the two complexes, maybe a “core” that has the most properties of both. IRead more

I am trying to learn about the effects of knot mutation on the hyperbolic manifolds obtained via hyperbolic Dehn surgery, and I’m currently reading Ruberman’s paper “Mutations and Volumes in $ S^3$ ” (in particular, see p.190-191, and p.212-213) and Christian Millichap’s paper (available here: https://arxiv.org/abs/1209.1042 ; in particular, p. 8). In these papers, weRead more

I flew from CBR – Canberra [35.2809° S, 149.1300° E] to ADL – Adelaide [34.9285° S, 138.6007° E] on Tuesday and noticed on the inflight map that it was very close to being perfectly west. As you can see from the lat/long pairs, it’s not far off. I was wondering if there were other airportsRead more
