When running the following code in a ROS melodic package:

I'm getting the following error even though Gazebo…

As the title says. If you watch the demo enough you will notice that >50% of the time the pilot will be matched up against themselves.
We might need to look into an alternate random number generato…

The `mixGamma` function should "fix" its result if the popcount is too low, but in its current version it is doing the opposite.

Just a heads up: your randomNumber function is biased (so probably not suitable for cryptographic purpose). See http://www.pcg-random.org/posts/bounded-rands.html for details (specifically "FP Multipl…

Things still evolve in the PRNG world. Mersenne Twister was the de facto standard ten years ago, but newcomers, such as PCG (https://github.com/imneme/pcg-cpp) have desirable properties such as:

There's a variety of modern PRNG algorithms we could choose from, with various tradeoffs around speed, memory, predictability, complexity, miscellaneous statistical properties, and also amenability to…

I am stupid about cryptography so please be kind if this is a stupid point.
Reading about the supposed shortcomings of Math.random(), I looked around and found that PCG is said to be good. Since I'…

Looking at: https://github.com/sjjamsa/prw/commit/f832179e21e2ec8771a570425f357eefb2724827 on a K80-node:

To seed random number generators, statismo uses the result of `std::time(0)`. This is problematic because `std::time(0)` returns the time passed since epoch, measured in _seconds_. If multiple threads…

Currently it is alias for `mt19937`. `mt19937` is not a bad generator on its own, but it is not a good default. The reason is that MTs are excessively large, so `sizeof(default_random_engine) == 5000`…
