Why are most random number generators said to be "pseudo-random" rather than truly random? What is the difference between true randomness and pseudo-randomness? | Reading a book on programming they mentioned that the Random function for C# didn't actually produce random numbers, it produced pseudo-random numbers, but that this is acceptable for almost all situations. I'm a bit confused as to what they actually mean. My understanding is as follows:
My random number generator is ... | Let's start with the definition of deterministic. A deterministic process or system has one future for each state. In phase-space, the trajectories don't cross. So you can usually predict the future state of a particle given the particles current state.
Random processes/functions/systems (whatever) can have multipl... | 16 | 20 |
CMV: Saying that we are in a computer simulation is a meaningless, nonsensical statement | From time to time I come across a theory claiming that our universe is a computer simulation. [Here](http://en.wikipedia.org/wiki/Simulation_hypothesis)'s a Wikipedia article about it. I think it's a completely meaningless proposition.
It's similar to claiming that there is a parallel universe, completely separated fr... | Bostrom's argument that I've previously read suggests the following:
Let's say we are in a computer simulation (which can be argued is actually quite likely). What is the purpose of this simulation? Is it to simulate a particular point in past history, or to determine certain particular outcomes to certain particular ... | 54 | 126 |
