Markovprosessseja

Markovprosessseja, also known as Markov processes, are a fundamental concept in probability theory and stochastic processes. They describe a sequence of possible events where the probability of each event depends only on the state attained in the previous event. This is often referred to as the "memoryless property." In simpler terms, the future state of the system is independent of the past states, given its current state.

The core components of a Markov process are its states and transition probabilities. States represent the different possible conditions or outcomes of the system. Transition probabilities quantify the likelihood of moving from one state to another in a single step. These probabilities are often represented in a transition matrix.

Markov processes have wide-ranging applications across various fields. In computer science, they are used in algorithms for natural language processing, speech recognition, and search engines. In finance, they model stock prices and credit risk. Biology utilizes them for population dynamics and genetic modeling. Physics employs them to study particle movement and quantum systems.

A key concept associated with Markov processes is the Markov chain, which is a discrete-time Markov process. For continuous-time processes, the term Markov process is more commonly used. The theory of Markov processes provides a powerful framework for analyzing and predicting the behavior of systems that evolve randomly over time.
