摘要：This paper studies a class of conic linkage problems, a generalization of the classical linkage problem involving subspaces, which frequently arise in applications such as multistage stochastic variational inequalities and conic complementarity problems. We propose a conic progressive decoupling algorithm (CPDA) that extends the progressive decoupling approach to conic constraints. By leveraging splitting techniques rather than Spingarn’s partial inverse framework, CPDA iteratively solves a generalized equation involving the monotone operator and updates projections onto the conic set and its dual. We establish the convergence of CPDA and analyze its rate of convergence under specific structural conditions. Numerical experiments on two-stage stochastic complementarity problems and multistage stochastic programming demonstrate the effectiveness of our approach compared to existing decomposition methods.
