Undefined start or end time with a limit on driving duration is not trivial. Well, routing school buses is already less than trivial. You have pickup & delivery. So there's a precedence constraint to orders. Child won't be kep

The thing is, all of these algorithms should be able to do well with arbitrary constraints. If it means saving less money then so be it. Many of these systems start optimizing some simple criteria and work fairly well. But with additional c

What does more specific means? You have a fleet of N vehicles, a list of M locations. You have to visit all in the shortest amount of time. Now add time windows for the locations, now add the constraint that out of these M locations you hav

Yeah, of course there are going to be pests. They used trial and error and the errors were local.

Interestingly, they have raised it without pesticides for that many years too.

by superpermutat0r 7y ago
Not that we do nothing. We can ban pesticides, return back to heuristic based agriculture where mistakes are localized and inventions are robust and of limited scale. Pesticides are mostly used for crops that humans do not eat directly. Foo

Schedule optimization in various industries. Delivery, health care, public transit. Any industry that has a workforce that needs optimizing.

These products can only be successful if tested for several generations. Pesticides also had a similar narrative and ended up being used in large quantities. Their effects on environment and human health are only discovered today and were u

Anything related to optimization that can be done tractably with heuristics, intractably with optimal algorithms. You end up going from a first customer tweaking what they want, to fulfilling feature requests from a group of customers, to e

Tyson Foods, the biggest chicken firm, gives (sells) chicken to family owned farms that make the decision to cram the chickens in small space, and then Tyson Foods buys back the big chickens. The business is done in a way so that Tyson Food

Contraction hierarchies[0] are a nice extension over which A* works even better and I believe these are used in osrm. I read a paper by Microsoft Research where they optimized the setting to enable shortest path routing in average of 5 memo

Unfortunately it's just the way advanced countries work. The society there is not made for people. So people do not have offspring and do not want to live. Although it's quite interesting that South Korea turned unfit for habitati

Yeah, but the reason GMOs started was to improve yields for livestock-feed related plants and is the reason GMOs exist today (if we ignore cotton, which is GMO-ed primarily for the clothing). I'm pretty sure soybean is nutrient dense l

by superpermutat0r 7y ago
GMOs for human consumption are not necessary. Enormous amounts of plant biomass are grown to feed livestock. GMOs also have an issue of exposing the once very inert system to black swan events, health or environmental issues. Similar thing

But squaring numbers is paralellizable. You pick an exponent you want and take a modulus only later. Iterative squaring is also trivial if exponent is a power of two. Calculating x^(2^t) mod n should take no time on any computer. I think th

Good correction, I meant beef, it's linked. Although USA does seem to avoid Brazilian soybean and beef.

What do the EU and USA do? Import more soybeans for their growing livestock industry. No penalties for anything, only rewards.

Of course it is. So is JavaScript. I've done stuff in C, C++, Haskell, python and am now writing primarily in js. Nothing weird there. I fight more with libraries than with the language.

Another good question in similar Spirit, why did we wait so long for wheels on suitcases?

No ingredient is healthy or unhealthy. Diet can be that or not. Having more vitamins, or other stuff means nothing. Body thrives on variability not on some optimality based on nutrient amounts.

You should not use Tesseract for subtitles that blend with the colorful background. Some leptonica magic can extract that yellow stuff pretty easily. OpenCV is not as powerful for it, although it does have some leptonica functionality. I&#x

You need good dictionaries, giving you all possible translations of a word both ways. Given that subtitles in both languages will have matching sentences very closely you can easily determine (be it some counting criteria, simple linear mod

Well, if I take 1 intercontinental flight every year, then my savings on some other stuff are pretty negligible. Same thing if I eat water intensive crops or meat. I can keep the tap open as long as I live and I would not waste the water sp

Hashed probably means that some features are mapped to a desired perceptron weight via a hash function. This serves as an implicit regularization and can be much more efficient (no need for a predetermined feature vector, sparse representat

Stepping aside is the finest display of lack of skin in the game. Something fails, you can just leave, while not returning any of the bonuses you "earned" for your "finest" work.
