Improve random number generator

Ulf Lorenz — Fri, 09 Aug 2024 21:27:02 -0000

As it happens, I have recently heard a talk that said feeding a RNG with a number is not a good idea; you want to hash the number first. That should maybe be added: The user seed is not used directly, but hashed first.

Attention: std::hash() is not guaranteed to hash anything.

Add some more operations to State

It turned out that adding/subtracting a constant to a state is occasionally quite convenient.

-In many cases, you just want to output expectation values to a file for manual inspection. That is currently pretty cumbersome and could be added to the ExpectationValueObserver. Also, the observer is currently missing the standard deviation, that could also be added.

Also, the observer is currently missing the standard deviation, that could also be added. Finally, the interface could be somehow ... smoother to use.
