Proposal: Hull-Dobell Theorem

Timed out and enacted, 7-1. Josh

Adminned at 25 Mar 2022 13:29:08 UTC

If “Simplification for the early days of a new dynasty” was not enacted, this proposal does nothing.
Then, if “More Digits” was enacted, revert all changes made to the Ruleset due to “More Digits”.

Add a new Probulator Function with the following properties:

Name: Wavefunction Observation
Output range: An integer between 0 and 999, inclusive.
Forecast output: 19
Method: Return forecast output and then change the forecast output to 1821 times the current forecast output plus 763 modulo 1000.

Add a material to the list of Materials with the name of Electron Microscope and a Function of Wavefunction Observation.

When c ≠ 0, correctly chosen parameters allow a period equal to m, for all seed values. This will occur if and only if:

  1) m and c are relatively prime,
  2) a − 1 is divisible by all prime factors (2,5)of m ,
  3) a − 1 is divisible by 4 if m is divisible by 4.


iter(n+1) = (a * iter + c) mod m


m = 1000
c = 763 satisfies 1
a = 1821 (1820 satisfies 2 & 3)

I’m very worried that this dynasty is going to heavily favour maths students.

But why is it important to have a period of 1000 and not 500?

Not that it’s important per se, but I think the point is more along the lines of “you don’t get every possible number as an output”. ^^

> I’m very worried that this dynasty is going to heavily favour maths students.

So far the Algorithms that have been proposed are either:
- Math-based like this one, but with predictable output so while _someone_ needs to do the math to figure out what the next numbers will be, others that are less math-enclined can look at the published sequence. This assumes that you trust the publish sequence is correct, mind you, but at least you don’t need to do the math yourself.
- Oracle-based, like the S&P 500 opening price one.

Things don’t have to be super math-heavy if we don’t want them to, we can propose algorithms that are fun for everyone. =)

Having a period of 1k solves the problem of “More Digits”, in which that might be unable to generate a particular number from 0-999 if any other Dynastic Rules wants it

I think I feel like having weird lacunae in the output dispersal creates game mechanic opportunities rather than closing them?

@Roujo the comment box on this proposal makes me want to cry
