WebMay 26, 2024 · Abstract. We study branching Markov chains on a countable state space $\mathscr {X}$, where the base Markov chain is transient and irreducible. Our focus is on the limit behaviour of population ... In probability theory, a branching process is a type of mathematical object known as a stochastic process, which consists of collections of random variables. The random variables of a stochastic process are indexed by the natural numbers. The original purpose of branching processes was to serve as a mathematical … See more The most common formulation of a branching process is that of the Galton–Watson process. Let Zn denote the state in period n (often interpreted as the size of generation n), and let Xn,i be a random variable … See more The ultimate extinction probability is given by $${\displaystyle \lim _{n\to \infty }\Pr(Z_{n}=0).}$$ For any nontrivial cases (trivial cases are ones in which the probability of having no offspring is zero for … See more Consider a parent can produce at most two offspring. The extinction probability in each generation is: with d0 = 0. For the … See more In multitype branching processes, individuals are not identical, but can be classified into n types. After each time step, an individual of type i will produce individuals of different types, and $${\displaystyle \mathbf {X} _{i}}$$, a random vector … See more Along with discussion of a more general model of branching processes known as age-dependent branching processes by Grimmett, in which individuals live for more than one generation, Krishna Athreya has identified three distinctions between size … See more Branching processes can be simulated for a range of problems. One specific use of simulated branching process is in the field of evolutionary biology. Phylogenetic trees, for example, … See more There are many other branching processes, for example, branching processes in random environments, in which the … See more

WebMar 23, 2015 · In practical development most optimizations rely on making simplifying assumptions about your data vs. applying a markov predictor. So if you wish to take advantage of branch prediction, know your data and organize it well. That will either improve your prediction, or allow you to skip it altogether.
