Identification of optimal policies in Markov decision processes [PDF]

, 2010
summary:In this note we focus attention on identifying optimal policies and on elimination suboptimal policies minimizing optimality criteria in discrete-time Markov decision processes with finite state space and compact action set.

Realistic Representation, Dynamic Evolution and Determinants of Institutional Quality in China

International Studies of Economics, EarlyView.
ABSTRACT The paper delves into the role of institutional quality in bolstering China's economic resilience post‐COVID‐19, CITIC‐Entropy. It divides institutions into basic and changeable categories, establishing an index system via the CITIC‐Entropy TOPSIS model.

SEMI-MARKOV DECISION PROCESSES AND THEIR APPLICATIONS IN REPLACEMENT MODELS

Journal of the Operations Research Society of Japan, 1985
We consider the problem of minimizing the long-run average expected cost per unit time in a semi-Markov decision process with arbitrary state and action space. Using the idea of successive approximations, sufficient conditions for the existence of an optimal stationary policy are given.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

A policy iteration algorithm for Markov decision processes skip-free in one direction [PDF]

, 2007
In this paper we present a new algorithm for policy iteration for Markov decision processes (MDP) skip-free in one direction. This algorithm, which is based on matrix analytic methods, is in the same spirit as the algorithm of White (Stochastic Models,

Predictive Ecosystem Health Assessment Under Land‐Use and Vegetation Dynamics in a Semi‐Arid Rift Valley Basin, Ethiopia

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation driven by rapid land‐use and climate‐driven vegetation dynamics increasingly threatens ecosystem stability in semi‐arid wetland basins, yet predictive ecosystem health assessments remain limited in Sub‐Saharan Africa. This study evaluates historical dynamics and future trajectories of ecosystem health in the Ziway‐Shalla Sub ...

Assessing Land Use Conflict in the Yangtze River Middle Reaches Megalopolis for 2030: Integrating Landscape Pattern Analysis and Scenario Simulation to Address Uncontrolled and Severe Conflict Zones

Land Degradation &Development, EarlyView.
ABSTRACT Land use conflicts (LUCs) significantly impact regional food security and ecological security. Identifying LUCs helps cut down ecological risks. This study focuses on the Yangtze River Middle Reaches Megalopolis (YRMRM) as a case, employing a landscape pattern approach to construct a land use conflict measurement model.

The Relationship Between Human Activities and Ecosystem Service Supply–Demand From the Perspective of Land Use Transformation

Land Degradation &Development, EarlyView.
ABSTRACT The equilibrium between ecosystem service supply and demand relationships (ESSDR) is essential for regional sustainable development. Understanding the relationship between human activity intensity (HAI) and ESSDR from the perspective of land use transformation (LT) is important for ecological management and governance.

Nonparametric Identification of Behavioral Responses to Counterfactual Policy Interventions in Dynamic Discrete Decision Processes [PDF]

This paper deals with identification in Markov dynamic discrete decision processes. It shows the nonparametric identification of the behavioral responses to counterfactual policy interventions that modify the one- period utility function.Dynamic discrete
