New Core-Halo decomposition method decentralizes fixed-point problems

Researchers have introduced a new method called Core-Halo decomposition to address challenges in solving large-scale fixed-point problems within decentralized systems. Traditional decomposition methods can introduce structural bias by truncating dependencies, but Core-Halo separates update ownership from read-only context. This approach allows for faithful implementation of the original fixed-point problem in multi-agent systems, achieving performance close to centralized methods while maintaining parallelism. AI

    Core-Halo Decomposition: Decentralizing Large-Scale Fixed-Point Problems

    We study solving large-scale fixed-point equation \(x^\star=\bar F(x^\star)\) with decomposition. Standard strict decomposition assigns each agent a disjoint block and evaluates updates using only owned coordinates. For most operators, however, a block update may depend on variab…
