Ask HN: What algorithms should I research to code a conference scheduling app
I'm interested in writing a utility to assist with scheduling un-conferences. Lets take the following situation for an example:

* 4 conference rooms across 4 time slots, for a total of 16 talks.

* 30 proposed talks

* 60 total participants

Each user would be given 4(?)votes, un-ranked. (collection of the votes is a separate topic) Voting is not secret, and we don't need mathematically precise results. The goal is just to minimize conflicts.

The algorithm would have the following data to work with:

* List of talks with the following properties:

* presenter participant ID

* the participant ID for each user that voted for the talk

I'd like to come up with an algorithm that does the following:

* fills all time slots with the highest voted topics

* attempts to avoid overlapping votes for any particular given user in a given time slot

* attempt to not schedule a presenter's talk during a talk they are interested in.

* Sugar on top: implement ranked preferences

My question: where do I start to research the algorithms that will be helpful? I know this is a huge project, but I have a year to work on it. I'm also not overly concerned with performance, but would like to keep it from being exponential.

Thank you for any references you can provide!
Fixed, thanks. What do you feel are some sensible systems used by the rest of the world? One that's hopefully hard enough to break but easy enough not to cause massive hassles.
Electric cars have insane torque and I've really started enjoying my drive again after buying one.

That said I paid $16.5k (post credits - on lease) for a 2017 Ford Focus Electric with 110m range.

If the real range of a used electric is within your commute range then a great deal can be had but new ones can also be found with good discounts.

"as far as we can all tell he is avoiding the horrible health effects"

No. Nicotine is a carcinogen. Forgive my surprise, but I'm absolutely blown away that this isn't common knowledge in 2017.

Edit: I appreciate the distinction that folks are making as far as what constitutes a carcinogen. Yes, the science we have today falls short of us classifying nicotine as a 'complete carcinogen'. If that makes you sleep better, then ok, but the science shows carcinogenicity in vitro, and substantial ability to promote tumor growth, metastasis, and recurrence in vivo [0][1][2][3].

Your friend is also potentially exposing himself and those around him to formaldehyde and diacetyl and so on, which is present in many e-cigarette liquids.

Folks: eat healthy, get a bit of exercise, read good books, and most of all, develop relationships with people you truly trust. If you find yourself needing to rely on smoking or drinking to get you through the week, take a step back and garbage-collect your life and decide if you're living the life you want, or if it's a life that's in need of radical restructuring.

If you were writing bank app in COBOL on mainframe 24X7 for many decades, you would have probably found it intuitive, productive and high value as well. The problem is that for most people scripting is not their day to day job. It's something you do for may be a day after you write month worth of code. If your scripting language is ugly and unfriendly you will tend to forget it and basically have to re-learn it every time you try to use it. That's not a good or productive experience for people who are writing 10 lines of script after long intervals.

While there are a lot of carcinogens associated with smoking, there doesn't seem to be a consensus that nicotine is one of them:

> Although there is insufficient evidence to classify nicotine as a carcinogen, there is an ongoing debate about whether it functions as a tumor promoter. In vitro studies have associated it with cancer, but carcinogenicity has not been demonstrated in vivo. There is inadequate research to demonstrate that nicotine is associated with cancer in humans, but there is evidence indicating possible oral, esophageal, or pancreatic cancer risks. Nicotine in the form of nicotine replacement products is less of a cancer risk than smoking. Nicotine replacement products have not been shown to be associated with cancer in the real world.

https://en.wikipedia.org/wiki/Nicotine#Cancer

The fact that it's other compounds that are carcinogenic rather than nicotine in no way changes the effects of second-hand smoke.

Postgres is going through some of these issues as well with ICU support. They don't necessarily have room for normalized strings in indexes, conversion is slow, and hashing also has trouble deciding if strings are identical.

I've been trying to get some ideas together about how to get around these issues. The Unicode Comparison Algorithm doesn't clearly define how to do incremental comparison (for string sorting, or traversing a trie etc.), but it seems that ICU already does some optimizations, such as discarding the longest common prefix in its strcmp via binary comparison, and then only converting the distinguishing character position.

Varies from person to person. After my cat died last year I started remembering each and every photo I had taken in different places over the years and somehow I lost track of a single photo (I'm not sure how it never got put in a single cloud photo service but I suspect it's because I took it on a camera, not a smartphone) that stood out to me because I remember it as probably the happiest he ever looked. I felt pretty terrible given of all the digital hoarding I do I couldn't keep track of one stinking picture that would mean more to me than hundreds of 4K movies. I'm a bit more liberal with my picture taking now knowing what I went through after the death of a cat and with people it would be worse.

Hate to be a skeptic -- or realist -- (and also risk downvotes) but here goes.

No matter what we try to do, it's looks like an Un-winnable battle. Unless Tobacco is outlawed, it's almost impossible to fight the entity known as "Big Tobacco".

They have an army of lobbyists, congressmen, senators, and all other power decision makers in their pockets, and using a combination of the above people, they get BILLS signed into LAW that legalizes a lot of things that would be otherwise be CRIMINAL, and on top of that, have very shady, but highly effecting marketing schemes and PR that they perform, to target the crowd most susceptible to succumbing to tobacco - teenagers, young adults, and (young) military men.

> AND THEN CAME THE CHRISTMAS CARDS.

Seems like a super f*king nice gesture, right? Until you hear what Big Tobacco sited as their motivation for the program.

No, it uses the quartz crystal for timekeeping. It keeps time like any other digital watch, only it outputs that time by controlling the rotor's speed, and gets its power from the rotor.

It could keep time mechanically instead and still use electronics to maintain the rotor's speed. But in fact it uses a quartz crystal.

I struggled for 2 years to study Chinese here in Taiwan. [...] I started reading the Bible every day

I, too, went to Taiwan when I began learning Chinese. It was very interesting, but ultimately a waste of time for anything except visiting the lovely museums, developing an early (in my Chinese linguistic education) feel for the transition between traditional and simplified Chinese characters, and the political reality of Taiwan's steadfast refusal to accept communist pinyin - a clearly and embarrassingly superior romanization system to anything Taiwan's academics could ever muster.

What I later learned (on the mainland) was that speaking to a wide variety of people with a wide variety of accents about a wide variety of every day matters and things of interest was the more efficient way to learn, but also learn to understand and be understood both verbally and in writing. Of the 1.4 billion people in mainland China, over sixteen years I've met perhaps ten who gave a damn about the bible, and nine out of ten were clearly and literally impoverished.[0]

I would wager that this is the source of your issues: frankly, nobody cares. You are learning a vocabulary without practical community or utility. It may be very important to you, and perhaps Taiwan has some happening churches, but in the context of Chinese language it's totally irrelevant to almost everyone.

> It might when creators stop creating - which, arguably, is already happening.

This is ok, perhaps even desirable. Ultimately, the market for music is already so oversaturated that more artists aren't really "needed" (that is to say, there is much more than enough music to service demand, not that more good art isn't valuable), and most non-elite artists would welcome reduced competition.

> There aren't many people arguing that the 2010s have been a better decade for music than the 60s to 90s.

Well either way that is a totally subjective argument that cannot ever be concluded definitively, there is so much more music produced today than in the 60s-90s that it'd be impossible to even make a fair subjective judgement regarding which decades produced "better" music. Certainly, I think everyone can agree that stronger economic incentives do not necessarily mean better work is produced and there are those who suggest that the opposite is true.
Until Amazon is offering simulcasts they're not really competing.

But, yes! It's absolutely amazing what goes into modeling traffic as accurately as possible. When we expanded to model pedestrian traffic as well, we even went so far as to build a mock store.

It's fascinating to see how small changes can influence traffic and alter the throughput. Simple things, like frequency of signage has a large impact. There are also regional differences where whole regions will, as an average, drive very differently.

You can run all the models, collect all the data, and someone will still get drunk and reverse the wrong way on a one way street. You'll never get perfect predictions and so there are constant changes being made. That kept it interesting.

What I worked on was all proprietary. It'd be interesting to see an open source project in this arena.

Yes, make the unfortunate pay even more. And it is the poor who are heavy smokers. There was a Russian joke when the government announces that alcohol price is going up so the boy is asking his dad if he is going to drink less and the father replies that probably the son will eat less instead. And ciggies are still in shops. Making it more expensive is a dumb idea.
I don't get what point you would be making if your "a few of its models" comment were true. Obviously any Fitbit that would come up in the context of an Apple Watch discussion is going to be one with purepulse. And in fact according to https://www.fitbit.com/purepulse there are 4 models in addition to Ionic that have it, i.e. 5 out of 8 trackers.

I don't know where you're getting the "or it senses a heart rate reading that's greater" part. Outside of workout mode it measures intermittently when you're still according to https://support.apple.com/en-us/HT204666 "When does Apple Watch measure your heart rate".

There's more to technology than hardware. Apple Watch can't do continuous all-day heart rate like Fitbit does even though the hardware is largely the same.

Long since past the point of smokers in Australia and NZ paying their own healthcare costs. Smokers subsidise the public healthcare system.

Unfortunately, the statistics are often muddied by externalised costs being assumed to include ~50k/year of lost life per smoker along with 'lost future income taxes'.

Generally smokers die earlier and more quickly. Ironically, living a very long life might actually cost society more due to many more years of intensive healthcare costs at the end of a long life.

I once heard an actuary claim that the tobacco taxes paid by smokers in NZ, if used for private health insurance for the individual, would afford the absolute best health cover available with funds to spare.

I apologise for not citing sources for the above claims. Quite frankly I am lazy and it would take some time (I have spent hours researching this in the past). You'll just have to take this as opinion.

We now have the technology to make available the great majority of human knowledge and culture to a vast amount of humanity for free. I'd call that a very positive state both for the people receiving it and the benefits it would bring to the world.

And the only thing stopping us is that certain people would like to be paid. It's the same argument with cheap generic drugs for the third world. At some point you have to incentivise research. But also, at some point you have to consider the benefits to the rest of society too.
