The article is about startups mostly. There’re lots of non-technical founders who think they can outsource everything and build a company and it won’t work. I tried to provide some guidelines in the article.

I also found out about tiered vectors only in this thread. At the time of implementation I tried to Google for something like this but didn't find.

I mentioned that extension in the published paper, but complexity of access becomes O(d) where d is number of dimensions.

Yes, the structure is sensitive for that and benefits a lot from using reserve(). I need to add automatic restructuring to maintain perfect k.

It seems I need to add automatic restructuring to the structure, so it would maintain perfect lengths of DEQs

by igushev 7y ago
I also need to add automatic restructuring when it expands or shrinks significantly.

Thanks for feedback!

Interesting that some people found an article about tiered vectors, I didn't find it back then. I implemented this structure many many years ago and also published in Bauman Moscow State Technical University magazine back in 2012: htt

That is true. The complexities in Big O notations, but I put all real-life measurements in README.md, so readers could see. On small item counts the complexity of data structure itself makes it performs worse comparing to std::vectors, only

by igushev 7y ago
That's a good point. That would make computation of indexes much more complicated though

by igushev 7y ago
That sounds like trees are silver bullets but they're not and that's why we have variety of basic data structures.

Thanks for feedback! Any naming suggestions? :-)

Thanks for feedback! I’ll update the README.md

DEQs also allocate internal arrays with hardcoded size only (8 in std, if I remember correctly)
23.
by igushev 7y ago
I need to read the paper, but on high-level looks indeed similar.
24.
by igushev 7y ago
Correct. I need to add automatic restructuring. Currently structure sensitive and benefits a lot from using reserve() method

DEQ has floating starting index. When you push or pop, you just changing this index. The implementation in the repository also have custom implementation of DEQs which is even more optimized for this structure.
26.
by igushev 7y ago
Insertion and deletion from DEQ indeed is linear, but in all of DEQs in the structure only one (!) needs insertion, the rest are just popping/pushing front/back.

At the time I was making research, I found one or two, don’t recall from top of my head. Majority of travel apps focus on hotels and/or tickets, not points of interest. The one which focus on points of interest, usually tries to give u

Also part of functionality which I wanted to add, is to for user to check what stage he/she at given moment and app would adjust the schedule, for example, user can’t make it today for museum A therefore it rescheduled for tomorrow and

During real live testing I found that it might be appealing to follow this kind of schedule, since there is no need for decision making. I realized why tour buses and cruise ships are popular.
