Forging with optimal back-pressure profile using sequential approximate optimization
Nihon Kikai Gakkai ronbunshu, 2014 This paper proposes a method for determining optimal back-pressure profile in forging using a sequential approximate optimization (SAO). In forging, it is important to minimize an unfilled area for improving the product quality. To achieve this objective,

A sequential approximation framework for coded distributed optimization [PDF]
2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017 Building on the previous work of Lee et al. and Ferdinand et al. on coded computation, we propose a sequential approximation framework for solving optimization problems in a distributed manner. In a distributed computation system, latency caused by individual processors ("stragglers") usually causes a significant delay in the overall process.
