complexity theory – Reducing 3-coloring problem to trio representatives

A group of students is divided into trios – groups of 3 members. Each student can be assigned to more than more trio. We want to assign their representatives, by choosing exactly one member of each trio. Is such assignment possible?

My goal is to use polynomial-time reductions to transform 3-coloring of a graph into this problem. However, I’m stuck on the correct representation.

  • If each vertex is a different student and edges represent being in the same trio, how do I separate trios?

  • If each node represents a trio, what could be a sensible meaning of the edges?

I suspect that since a 4-clique has no adequate 3-coloring (which could also mean that 4 trios with the same three members have no possible representative assignment), the latter option could be more sensible, but I’m not sure on how to proceed with this reduction proof.

Multi-factor – Why are GoDaddy's customer service representatives requesting two-step verification codes?

When you contact GoDaddy's customer service, either by chat or by phone, they often ask for both a PIN code and a two-step verification code (which they mistakenly call "authentication codes" Google ").

Then the PIN code can be found when you log into your GoDaddy.com account, but the two-step verification code is something you need to get from the app, service or hardware device you are using to generate two-step verification codes (compatible options listed here).

Typically, two-step verification codes are time-based one-time use codes that I only used to log into my own accounts via my own web browser or mobile app on my own devices . I have never had other customer service representatives from other companies request these codes. Usually they just ask for PIN codes (if the service is configured to use them).

Why would GoDaddy Customer Service require two-step verification codes? Are they actually using them to log into your account on their side? If so, how could they do this without having your password? Also, is it a bad security practice to require customers to share two-step verification codes with someone else in this way?

I found this related question from someone concerned about customer service representatives asking for PIN codes here, and people agreed that even this is bad security practice.

Abstract algebra – Coset representatives of a subgroup

Let $ G $ be a group and leave $ H $, $ K $ to be normal subgroups $ G $ such as $ H <K $. Assume that $$ G = Hx_ {1} dot { cup} Hx_ {2} dot { cup} dots dot { cup} Hx_ {n}. $$ C & # 39; is, $ {x_ {1}, dots, x_ {n} } $ are representatives of coset.

Since $ H $ is also a subgroup $ K $, we can talk about good sets of $ H $ in $ K $.

I would like to know if there is a way to find out who are the representatives.

I have tried the following:

Let $ x_ {1}, dots, x_ {k} $ to be the elements that are in $ K $, and $ x_ {k + 1}, points, x_ {n} $ those in $ G $ but not in $ K $.

So, $$ K = Hx_ {1} dot { cup} Hx_ {2} dot { cup} dots Hx_ {k}. $$

It is trivial that $ Hx_ {i} subseteq K $ because $ x_ {i} $ is in $ K $ and $ H $ is a subgroup of $ K $. On the contrary, if $ g in K $, $ g in G $, therefore $ g in Hx_ {j} $ for some people $ j in {1, dots, n } $. Therefore, $$ Hg = Hx_ {j}, $$ therefore $ x_ {j} en Hg subseteq K $.

Is it correct? Thanks in advance!

Why should clandestine immigrants be counted in the census and have congressional representatives and electoral votes when they should not even be here?

"Why should illegals be counted in the census"
because the US Constitution says that they should do it, but thanks for this proof again, the GOP has no idea what the Constitution contains.

"should I give this answer a thumbs up"
Only if you want to provide evidence again does the government have any idea of ​​the content of the Constitution.

What is cloud hosting?

Cloud hosting technology is the latest generation of web hosting, thanks to which customers can rent a virtualized and scalable structure dynamically as needed.

Unlike the dedicated server, with which users must pay for all server resources to ensure that they are available during periods of heavy traffic, the cloud server optimizes them. resources available on request and puts them to use elsewhere when traffic drops, which means you only pay for what you use.
