Neurodynamic approaches for multi-agent distributed optimization.

Area of Science:

• Distributed Optimization
• Control Theory
• Artificial Intelligence

Background:

• Multi-agent systems require efficient distributed optimization strategies.
• Handling common constraints in these systems is a significant challenge.
• Existing methods may involve complex variable transformations or auxiliary information exchange.

Purpose of the Study:

• To develop novel continuous-time neurodynamic approaches for multi-agent distributed convex optimization.
• To address problems with common constraints without introducing auxiliary variables.
• To provide algorithms for both nonsmooth and smooth cost functions.

Main Methods:

• Utilizing l1 and l2 penalty methods to transform linear consensus constraints into the objective function.
• Developing differential inclusions with projection operators for nonsmooth cost functions.
• Designing finite- and fixed-time convergent algorithms for smooth cost functions using an average consensus estimator.

Main Results:

• The proposed methods avoid auxiliary variables, relying solely on primal variable information exchange.
• Asymptotic behavior and convergence properties are analyzed for differential inclusions, even without convexity.
• Finite- and fixed-time convergence is demonstrated for smooth cost functions.
• Numerical simulations validate the effectiveness of the neurodynamic approaches in multi-agent environments.

Conclusions:

• The presented continuous-time neurodynamic methods offer an effective solution for multi-agent distributed convex optimization with common constraints.
• The techniques are versatile, addressing both nonsmooth and smooth cost functions with proven convergence properties.
• These approaches provide a robust and efficient framework for complex multi-agent coordination problems.
