A weird "yaw" behavior in simulation using atan2() function

I'm working on an application, a simulator, where a quadrotor flies from waypoint to waypoint. In my code I've implemented a function to calculate the yaw using atan2 function. But when the quadrotor turns over 360° it doesn't move through the…

Which data structure(s) to back a Final Fantasy ATB-style queue? (a delay queue)

Situation: There are several entities in a simulated environment, which has an artificial notion of time called "ticks", which has no link to real time. Each entity takes it in turns to move, but some are faster than others. This is expressed by a…

Generating Random Variables with given correlations between pairs of them:

I want to generate 2 continuous random variables Q1, Q2 (quantitative traits, each are normal) and 2 binary random variables Z1, Z2 (binary traits) with given pairwise correlations between all possible pairs of them. Say (Q1,Q2):0.23 (Q1,Z1):0.55…

Can I have multiple independent random number generators in R like I can in C++?

I have many independent random processes (arrival processes say) that require me to generate random numbers. I want to use common random numbers for each of these processes that I can compare how different policies perform when controlling these…

Discrete Event Simulation without global Queue?

I am thinking about modelling a material flow network. There are processes which operate at a certain speed, buffers which can overflow or underflow and connections between these. I don't see any problems modelling this in a classic Discrete Event…
