WebAug 1, 2016 · However, I need to simulate continuous time markov chain (CTMC) transition times for birth & death process using C++. I came across this github project which simulates regular CTMC, where the row sum of all lambda will be 1. But in case of birth-death process (M/M/c/K), it will be zero. So I can't exactly use it for my purpose. WebThe Birth Death Chain is an important sub-class of Markov Chains. It is frequently used to model the growth of biological populations.
