time, and approximates Per (A) to within ±ε ‖A‖ additive error. A major advantage of Gurvits’s algorithm is that it works for arbitrary matrices, not just for nonnegative matrices. This makes it highly relevant to quantum optics, where the permanents of boundednorm complex matrices play a central role. (In particular, n × n permanents arise as the(More)
We present an approach for dynamic information flow control across the application and database. Our approach reduces the amount of policy code required, yields formal guarantees across the application and database, works with existing relational database implementations, and scales for realistic applications. In this paper, we present a programming model(More)
cases culled from the gynaecological reports of the Liverpool Royal Infirmary, but also for a very carefully compiled list of his operations performed in private, with their results and after-histories, has adopted a simple and efficacious procedure which appear to meet the demand alluded to. The simplicity of the operation will be shown from the(More)
In the next two lectures we study the question of dynamic optimality, or whether there exists a binary search tree algorithm that performs ”as well” as all other algorithms on any input string. In this lecture we will define a binary search tree as a formal model of computation, show some analytic bounds that a dynamically optimal binary search tree needs(More)
