Title：A primal-dual online algorithm for the k-server problem on weighted HSTs
Abstract：In this talk, we show that there is a 2.5Lln (1+k)-competitive randomized algorithm for the k-sever problem on weighted Hierarchically Separated Trees (HSTs) with depth L when n=k+1 where n is the number of points in the metric space, which improved previous best competitive ratio 12 L ln (1+4L (1+k)).

Title: Smart control algorithm via coupled forward-backward neural nets and federated machine learning
Abstract:We develop a smart control algorithm via coupled forward-backward neural nets and federated machine learning. The constraint of our control system is represented by a stochastic differential equation (SDE) with Levy jumps and boundary reflection, which includes many practical buffer storage (i.e., queueing) systems, scheduling, routing and control systems as special cases. The objective functional can take different forms corresponding to their associated practical systems. The optimal control policies are proposed by designing a smart algorithm through coupled forward-backward neural nets and federated machine learning with time evolution. The policies cover both conventional parameter control (e.g., drift and diffusion control) policies and jump size control (e.g., impulse and singular control) policies. In real-world systems, these policies may represent the demand/resource rate, pricing, and sequential batch assembly policies. Simulation examples will be provided to illustrate the effectiveness of our developed algorithm and policies.
