I admit, I struggled a bit with the polynomials as I don't work much with them anymore, I still don't see any direct application for them even after years of working in scientific computing. Therefore, I see them as a graduation test only, meaning "If we can force you to learn this, then we can force you to learn anything.".
Just for that you fail the exam.
I think the point the GP was making was that, yes the US military can instantly and overwhelmingly wipe out any civil resistance. However that is entirely dependent on said soldiers of the US military actually following those orders. If there was a civil insurrection, there is a real possibility that soldiers would simply refuse to open fire on civilians and also possible that they would simply join them.
Doesn't happen much, does it?
Look, left-wing parties are likely to do well in our next election, but no-one sensible here, left or right, wants to raise the corporation tax rate. These companies provide our jobs.
If a raise would be announced, ordinary people here would really start to protest.
Ireland is not the US, where lower-middle class working people will protest on the streets saying that Mario Antoinette should have more cake.
I'd like to see a game that isn't a click-fest, but still would offer some action and nice visuals. Something with the gameplay involving giving orders to partially autonomous troops. After giving orders, you could watch and see how they fare and perhaps give some further orders, maybe with some possible penalty incurred for breaking radio silence. Or in the setting of a Total War type of game, there could be a limited number messengers who would take time to reach the troops and even have a chance to fail in delivering your orders.
Scourge of War: Gettysburg and its predecessors Take Command: 2nd Manassas and Take Command: Bull Run pretty much work that way. The graphics are dated (think Medieval: TW quality) but functional enough, the gameplay fairly slow and meticulous. Most battles start with 5-20 minutes of maneuvering into attack positions, after which you order your divisions/brigades their set targets and watch them march into the fray. If and when things start looking bad you start to micromanage individual batteries and regiments. That's when it gets really hectic and interesting. Or you can play Empire: TW and watch the beautifully rendered but historically ridiculously inaccruate soldiers run up and down mountains on a tiny battlefield while being bombarded by overpowered artillery.
Multigrid is theoretically O(s), so I don't immediately see how this is such a huge leap. Of course the actual complexity also depends on the problem and the implementation. Maybe their method.is applicaple to a wider variety of problems.
Also, the "iterated sparsifying" sounds a lot like algebraic multigrid.
Why is this a troll?
Because anyone who points out that modern greens have abandoned real convervationism for made-up issues like CO2 "pollution" gets modded a troll on
