An extremum seeking-based approach for Nash equilibrium seeking in N-cluster noncooperative games
Published 2021“…Thirdly, different from most of the existing works that adopt singular perturbation to analyze the stability of extremum seekers, this paper establishes the convergence results via Lyapunov stability analysis, which is novel and provides some new insights on the analysis of extremum seekers. A numerical example is provided to verify the effectiveness of the proposed method.…”

Robust pricing and production with information partitioning and adaptation
Published 2022“…In particular, we investigate the joint pricing and production problem by proposing a cluster-adapted markdown policy and an affine recourse approximation, which allow us to reformulate the problem as a mixed-integer linear optimization problem that we can solve to optimality using commercial solvers. Both the numerical experiments and case study demonstrate that, with only a few number of clusters, the cluster-adapted markdown policy and the partitioned-moment-based ambiguity set can improve mean profit over the empirical model---when applied to most out-of-sample tests.…”

Regional-privacy-preserving operation of networked microgrids: edge-cloud cooperative learning with differentiated policies
Published 2024“…By only transiting the global model parameters during the coordinated training process, the private NN models of each agent at the edge are also preserved to the MGs locally. Numerical studies validate that the proposed framework can effectively handle the complex privacy-preserving NMGs coordinated operation problem with collaborative learning through the DP-FDRL algorithm.…”

Computational rheometry of yielding and viscoplastic flow in vane-and-cup rheometer fixtures
Published 2024“…A planar two-dimensional computational analysis is presented to qualify traditional and fractal vane-in-cup geometries for accurate rheometry of simple viscoplastic fluids with and without slip. Numerical simulations based on an adaptive augmented Lagrangian scheme are used to study the two-dimensional flow field of yield-stress fluids within and around vane tools with N=3 to 24 arms for a wide range of Bingham numbers, B (i.e. the ratio of the yield stress over the characteristic viscous stress). …”
