Time-space lower bounds for undirected and directed st-connectivity on JAG models Je A. Edmonds Doctor of Philosophy 1993 Department of Computer Science University of Toronto Directed and undirected st-connectivity are important problems in computing. There are algorithms for the undirected case that use O (n) time and algorithms that use O (logn) space. The rst result of this thesis proves tha...

Some prior research has presumed that deference to “faith” constitutes an emotional goal. However, the epistemic nature of faith and its relation to evidence has been the focus of philosophical debate, both his...

In the near future, energy conservation and pollution reduction became two of the most significant factors in economic development and social circulate. For analyzing the issue, several models were applied involving the fields of mathematical optimization, economics theory, dynamics model and industrial management. Specifically, they are MARKAL model, Input-Output model, LEAP model and Systemic...
