If Google can "basically determine web standards", then I don't see how it's possible for anyone else to "still have a seat on the table". I mean, if they cared enough about it and were actually on the table in

Oh, wow. I couldn't really figure out which parts of AMPL were proprietary and I guess I immediately dismissed it after that without understanding how it worked. As for Pyomo, while at first glance I dislike the syntax (it's not a

I guess it doesn't matter that much, but if there were a common language, it would be a nice feature that would allow you to skip the middleman altogether and have simpler dependencies if you know which solvers you want. It's the

Maybe I was confusing my terms or something. I think of these as like an API as well, although packaged into a nice library that automates some stuff. So I guess I'll try to describe my ideal scenario instead. What I was thinking of wa

Thanks, but it was not really what I was looking for. I was looking for something that feels closer to a DSL than an API. In OR, a language like AMPL (IIRC, by Brian Kernighan) or GAMS is typically used where you define sets, variables, etc

Glad to see someone posted about COIR-OR! I've been looking at open source solvers for a while now to solve an MIP, and this one seems to be the best. There is this annoying thing about the whole ecosystem though, aside from the propri

Probably the wrong engine to test this with then. Although it's interesting nonetheless. It's pretty well known that chess engines have this trade-off between searching and evaluating. Among the consistent top 3 I suppose Stockfis

Thanks for that. My undergrad was Industrial Engineering but I always loved the Operations Research stuff (which I'm hoping will lead me to more CS-y stuff if I can get a job or a Masters or something). All that OR with LPs and MIPs wa

For something as well known as shortest path, no. One thing about LP/MIP formulations though, is that it's arguably easier to extend. Not to say there aren't tricks to modifying existing algorithms, but most of the time, ther

I have some idea how it MIGHT work, but it would be a very boring solution involving 'learning' Stockfish's parameters and HOPING to find improvements to something like integrating time management and search/pruning into

Does this mean it learns what to search? I wonder why they thought it was a good idea. I thought the whole point of MC was that pruning algorithms like the ones in chess wouldn't work for a larger search space.

For those of us who just want Linux on the phone, but don't know much about hardware and low level stuff: What can we expect? How powerful are these going to be? I guess asking how they compare to current phones performance-wise is not

I don't get the issue as well, but maybe from ignorance. Can't I just get the rust compiler in LLVM's IR form and bootstrap from there?

After this, do a bit of research on goal programming or other approaches to multiobjective optimization. It could really help and depending on the approach, it's not that hard. It usually just adds a bunch of constraints or some precom

And here I am, still waiting for the second edition of that book on learning Rust to be finished. I want to learn Rust for fun and I know I should probably just start on reading the book, but I keep making up excuses not to. I want my ++, -

Can someone explain simply what this means for projects like libreboot and coreboot? I'm always interested with this stuff and it's implications, but don't have the background to understand a lot of low level details. Is the

As much as I want a FLOSS phone to succeed, I have my doubts. Then again, I'm not sure how all the Matrix stuff works, but if I can't simply give someone my phone number and expect it to just work, I don't see how this can ha

As someone who first learned how to program by implementing PRNGs but never really digging deeper into it, I found this post very interesting to read. I do have an idea about some (small portion) of the things behind it, but I have no backg

I don't understand why this still looks scary to me. A while back after learning regex (though only at a basic level) I thought, maybe I can make my own custom C preprocessor as an exercise. Perfect right? I get to choose the syntax AN

As someone who was forced to learn Palmer style in school, I must say I always hated the capital Q. I don't know if I just couldn't get it right, or I never really saw it as legible, but it annoyed me that it looked too much like

Just curious, because I was thinking of using PulseAudio just for Firefox (which is kind of annoying). What's wrong with PulseAudio? Why did they stop supporting ALSA?

The Stockfish Makefile is probably the best example of this I've seen. It also does some advanced stuff I'm not sure I understand yet. Profiling, setting flags for CPU instructions and making profile builds, all with support for d

I'd say Python would've been the 'safe' and 'sane' choice, but maybe it's just my bias against Java and JavaScript talking. Just curious, has anyone ever heard off choosing to teach something like bash &#x

I used to think I understand Linear Programming, and the transportation problem. Is there a relationship between this and the Markov formulation? I'm totally confused now. Posts like this make me feel guilty about not reviewing them on

Interesting history! >Sorting is a mostly "solved" problem in theory, but as new hardware emerges different aspects of implementations become more or less important (cache, memory, branch prediction) This makes me wonder what o
