The discrete time –cost trade-off problem (DTCTP) is one of the main aspects of project scheduling. In DTCTP , we treat cost as a non-renewable resource and the availability of renewable resource per period has been neglected. It was recently suggested that the quality of project should also be taken into consideration. Therefore, when renewable resources and quality are considered, the traditi...

OF THE DISSERTATION Supervised Machine Learning Under Test-Time Resource Constraints: A Trade-off Between Accuracy and Cost by Zhixiang (Eddie) Xu Doctor of Philosophy in Computer Science Washington University in St. Louis, 2014 Research Advisor: Professor Kilian Q. Weinberger, Chair The past decade has witnessed how the field of machine learning has established itself as a necessary component ...

In this paper, a green transportation location problem is considered with uncertain demand parameter. Increasing robustness influences the number of trucks for sending goods and products, caused consequently, increase the air pollution. In this paper, two green approaches are introduced which demand is the main uncertain parameter in both. These approaches are addressed to provide a trade-off b...

-It is demonstrated that usual time-memory trade-offs offer no asymptotic advantage over exhaustive search. Instead, trade-offs between time, memory, and parallel processing are proposed. Using this approach it is shown that most searching problems allow a trade-off between C,, the cost per solution, and C,,,, the cost of the machine: doubling C,,, increases the solution rate by a factor of fou...

PROBLEM • Monotonically improve a parametric gaussian policy πθ in a continuous MDP, avoiding unsafe oscillations in the expected performance J(θ). • Episodic Policy Gradient: – estimate ∇̂θJ(θ) from a batch of N sample trajectories. – θ′ ← θ+Λ∇̂θJ(θ) • Tune step size α and batch size N to limit oscillations. Not trivial: – Λ: trade-off with speed of convergence← adaptive methods. – N : trade-off...

Living organisms can perform computations through various mechanisms. Understanding the limitations of these computations is not only of practical relevance (for example in the context of synthetic biology) but will most of all provide new insights into the design principles of living systems. This thesis investigates the conditions under which genes can perform logical computations and how thi...
