WebbFor example, our primal-dual algorithm for the Steiner Forest problem does not satisfy the 2-approximate complementary slackness conditions for every j, yet we can show that … WebbWe propose DISH as a distributed hybrid primal-dual algorithmic framework to handle and utilize system heterogeneity. Specifically, DISH allows those agents with higher computational capabilities or cheaper computational costs to implement Newton-type updates locally, while other agents can adopt the much simpler gradient-type updates.
