A Data-Driven Linear Programming Model for Energy-Optimal Metro Timetables
Shuvomoy Das Gupta, Qiuyu Fan, Bart P. G. Van Parys +1
We propose a data-driven linear programming model to compute energy-optimal timetables for networks operating under communications-based train control (CBTC); the model was develop…
Computer-Assisted Design of Accelerated Composite Optimization Methods: OptISTA
Uijeong Jang, Shuvomoy Das Gupta, Ernest K. Ryu
The accelerated composite optimization method FISTA (Beck, Teboulle 2009) is suboptimal by a constant factor, and we present a new method OptISTA that improves FISTA by a constant…
Nonlinear conjugate gradient methods: worst-case convergence rates via computer-assisted analyses
Shuvomoy Das Gupta, Robert M. Freund, Xu Andy Sun +1
We propose a computer-assisted approach to the analysis of the worst-case convergence of nonlinear conjugate gradient methods (NCGMs). Those methods are known for their generally g…
