A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Os impactos ambientais industriais da alca no Brasil

open access: yesEconomia Aplicada, 2005
This study is an attempt to estimate the industrial environmental impacts due to FTAA in Brazil. Based on these CGE model results from Tourinho and Kume (2002), we estimate the resulting changes of pollution emission and water and energy use levels in ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Neoclassical General Equilibrium Theory as a Source of Powerful Concepts, Although Confronted with the Complexity of Market Economies

open access: yesŒconomia, 2012
General equilibrium theory is an instrument for the analysis of market economies. The wide range of concepts used in general equilibrium stems from the complexity of market economies.

From General Equilibrium to Algorithmic Equilibrium

open access: yesQeios, 2023
Based on the Algorithmic Thinking Theory, this essay introduces the concept of “Algorithmic Equilibrium”, which can really exist and be used to replace, re-interpret, and/or synthesize all other kinds of equilibria, and to allow the coexistence of equilibria and various dis-equilibria in a unified, dynamic, and developmental panorama, thus exhibiting a

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
