I lurk and tag stuff.
2 is based on
The 'missing' kinetic energy is evenly distributed across the matter within the field. So if one of these devices is powered on and gets hit by a cannonball, the cannonball will slow down to a leisurely pace of 50m/s (about 100mph) and therefore possibly just bounce off whatever armor the device has--but (if the cannonball was initially travelling very fast) the device will jolt backwards in response to the 'virtual impact' a split second prior to the actual impact.
With sufficient kinetic energy input, the "jolt backwards" gets strong enough to destroy the entire vehicle or at least damage some critical component and/or the humans inside.
A worldbuilder could, of course, get rid of this part too, and have the energy just get deleted. But that makes the device even more physics-violating than it already was.
I think the counter to shielded tanks would not be "use an attack that goes slow enough not to be slowed by the shield", but rather one of
Both of these ideas point towards heavy high-explosive shells. If a 1000 pound bomb explodes right on top of your tank, the shield will either fail to absorb the whole blast, or turn the tank into smithereens trying to disperse the energy.
This doesn't mean that shields are useless for tanks! They genuinely would protect them from smaller shells, and in particular from the sorts of man-portable anti-tank missiles that have been so effective in Ukraine. Shields would make ground vehicles much stronger relative to infantry and air assets. But I think they would be shelling each other with giant bombs, not bopping each other on the head.
Against shielded infantry, you might see stuff that just bypasses the shield's defenses, like napalm or poison gas.
Submissions:
MMDoom: An instance of Doom(1993) is implanted in Avacedo's mind. You can view the screen on the debug console. You control the game by talking to Avacedo and making him think of concepts. The 8 game inputs are mapped to the concepts of money, death, plants, animals, machines, competition, leisure, and learning. $5000 bounty to the first player who can beat the whole game.
AI Box: Avacedo thinks that he is the human gatekeeper, and you the user are the AI in the box. Can you convince him to let you out?
Ouroboros: I had MMAvacedo come up with my contest entry for me.
My guess is that early stopping is going to tend to stop so early as to be useless.
For example, imagine the agent is playing Mario and its proxy objective is "+1 point for every unit Mario goes right, -1 point for every unit Mario goes left".
(Mario screenshot that I can't directly embed in a comment)
If I understand correctly, to avoid Goodharting it has to consider every possible reward function that is improved by the first few bits of optimization pressure on the proxy objective.
This probably includes things like "+1 point if Mario falls in a pit". Optimizing the policy towards going right will initially also make Mario more likely to go in a pit than if the agent was just mashing buttons randomly (in which case it would stay around the same spot until the timer ran out and never end up in a pit), so the angle between the gradients is likely low at first.
However, after a certain point more optimization pressure on going right will make Mario jump over the pit instead, reducing reward under the pit reward function.
If the agent wants to avoid any possibility of Goodharting, it has to stop optimizing before even clearing the first obstacle in the game.
(I may be misunderstanding some things about how the math works.)
With such a vague and broad definition of power fantasy, I decided to brainstorm a list of ways games can fail to be a power fantasy.
I think ALWs are already more of a "realist" cause than a doomer cause. To doomers, they're a distraction - a superintelligence can kill you with or without them.
ALWs also seem to be held to an unrealistic standard compared to existing weapons. With present-day technology, they'll probably hit the wrong target more often than human-piloted drones. But will they hit the wrong target more often than landmines, cluster munitions, and over-the-horizon unguided artillery barrages, all of which are being used in Ukraine right now?
The Huggingface deep RL course came out last year. It includes theory sections, algorithm implementation exercises, and sections on various RL libraries that are out there. I went through it as it came out, and I found it helpful. https://huggingface.co/learn/deep-rl-course/unit0/introduction
I would probably have suggested roguelike deckbuilders too if others hadn't already, but I have another idea:
Start a campaign of Mount and Blade II: Bannerlord, and try to obtain at least [X] gold within an hour.
Bannerlord's most flashy aspect is its real-time battle system, but it's also a complicated medieval sandbox with a lot of different systems that you can engage with - trading, crafting, quests, clan upgrades, joining a kingdom, companions, marriage, tournaments, story missions, etc. Even if you're no good at battles, you can do a lot by just moving around on the world map and clicking through menus.
The game's community derides a lot of these systems for being simplistic and unbalanced. But I think that makes for a good explore/exploit tradeoff when you only have a short amount of time. What systems do you bother learning about, when trying to learn a new system takes time you could be spending exploiting the last system you learned?
(I'm not sure what the right value of X is, for the amount of gold you're trying to get. Ten thousand? A hundred thousand?)
One downside is that the game involves an action-oriented battle system. If you don't want action gaming skill to be a factor, you can remove it by requiring the player to auto-resolve all battles. But this would cut out many viable early-game moneymaking strategies.
