Optimal Portfolio Selection in an Itô–Markov Additive Market
Risks, 2019 We study a portfolio selection problem in a continuous-time Itô–Markov additive market with prices of financial assets described by Markov additive processes that combine Lévy processes and regime switching models.

ASYMPTOTICS OF CONTROL PROBLEM FOR THE DIFFUSION PROCESS IN MARKOV ENVIRONMENT
Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2020 A stochastic optimization procedure and a limit generator of the original problem are constructed for a system of stochastic differential equations with Markov switching and diffusion perturbation with control, which is determined by the condition for ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space
Advanced Robotics Research, EarlyView.A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Advanced Science, EarlyView.SKALE 2.0 maps disease‐associated protein aggregation as a phase‐resolved structural process, linking mutation‐induced geometric perturbations to nucleation, elongation, and suppressor design. Across neurodegenerative proteins, the framework reveals cryptic aggregation vulnerabilities, separates phase‐concordant and phase‐switching mutations, and ...

Markov Switching Vector Autoregressive Modelling of the Nigerian Stock Price and Oil Price Series
Quantitative Economics Research, 2018 This article studied the relationship between stock prices and crude oil prices of Nigeria using a Markov switching model. Certain properties of the stock price series and crude oil price series such as breaks and stationarity, which are necessary before

Markov Switching Model for Financial Time Series [PDF]
Ovidius University Annals: Economic Sciences Series, 2021 Modeling financial time series is an important step for its forecast and risk evaluation when financial assets are involved. In this context, this article presents a Markov Switching Model for BET series recorded during the period Oct-2000 - Sept-2014 ...

Optimal Control with Partially Observed Regime Switching: Discounted and Average Payoffs
Mathematics, 2022 We consider an optimal control problem with the discounted and average payoff. The reward rate (or cost rate) can be unbounded from above and below, and a Markovian switching stochastic differential equation gives the state variable dynamic.
