>>1515>It's ridiculously complicated. It's a partition problem: How many ways can you add up numbers to get to 20? ... So I ran a script on Python to calculate some of this. It got to 22 by running over a weekend, and I couldn't get it to go any further.The trick to calculating this efficiently is to instead think about the expected end-of-turn score given that you have reached some current score. Suppose your strategy is to stop at 20. If you reach a score of 20, you will stop, so your expected end-of-turn score given your current score is 20. Simiarly, if you reach a score of 21, your expected end-of-turn score given your current score is 21, and so on. If you reach a score of 19, we can calculate your expected end-of-turn score given your current score by averaging the expected outcomes of your next die roll. If you roll a 1, you get 0. If you roll a 2, we have to look up the expected end-of-turn score given a current score of 19+2=21, which we already know is 21. And so on for 3 through 6. Using this method, we can calculate the expected end-of-turn score for lower and lower current scores until we finally reach what we want, the expected end-of-turn score given a current score of zero, as you have when you start your turn.
Letting expectation(score, stopping_point) be the expected end-of-turn score given a current score of "score" using a strategy where you stop at a score of "stopping_point", we can calculate as follows:
#!/usr/bin/env python3
from fractions import Fraction
from functools import cache
@cache
def expectation(score, stopping_point):
if score >= stopping_point:
return score
else:
return Fraction(1, 6) * sum(expectation(score + roll, stopping_point) for roll in range(2, 7))
for n in range(41):
print(n, float(expectation(0, n)), expectation(0, n))Runs in a fraction of a second.
This trick is very useful for solving otherwise hard probability problems.

the strength of robotics is something that hasn't been televised/sensationalized much aside from Boston Dynamics, but it's quite amazing what modern sensors can do.

>>1533Guns and missiles are just point and shoot. Aircraft have had targeting for decades, missile launch systems are completely computerized, heck computer-operated flak batteries were even a thing back in WWII on the German side.
I remember watching a military documentary from either the 90s or early 20s on "smart guns". It's been a long while since I watched it, but I think the gist was that the aiming sight was computerized and would give aiming information to the operator, and then the bullets themselves would somehow course correct mid-flight to ensure contact with the target. Ultimately the documentary revealed that the project was canceled, likely due to cost and the end of the Cold War, but also as a pragmatic decision; if you're only going to be fighting farmers with AKs, it scarcely makes sense to invest in a new weapon when the current one works fine. If the new Cold War with China heats up, though, I wouldn't be surprised if that project gets taken off ice and we start seeing crazy auto-targeting rifles in actual combat usage.
Unfortunately, wars are a great impetus for progress.
