and Ben Polak Introduction to judgment aggregation

This introduces the symposium on judgment aggregation. The theory of judgment aggregation asks how several individuals’judgments on some logically connected propositions can be aggregated into consistent collective judgments. The aim of this introduction is to show how ideas from the familiar theory of preference aggregation can be extended to this more general case. We …rst translate a proof o...

Pharmacokinetics of amphotericin B and flucytosine ANNEMARIE POLAK

The absorption of flucytosine from the digestive tract is very good but minimal with amphotericin B. For this reason, amphotericin B has to be injected intravenously. Fungistatic levels are achieved rapidly with flucytosine and slowly with amphotericin B, since the dose has to be increased slowly. Distribution of flucytosine in other body fluids is high, whereas with amphotericin B it is poor. ...

A modified Polak-Ribière-Polyak conjugate gradient algorithm for nonsmooth convex programs

The conjugate gradient (CG) method is one of the most popular methods for solving smooth unconstrained optimization problems due to its simplicity and low memory requirement. However, the usage of CG methods are mainly restricted in solving smooth optimization problems so far. The purpose of this paper is to present efficient conjugate gradient-type methods to solve nonsmooth optimization probl...

A globally convergent version of the Polak-Ribière conjugate gradient method

1 ABSTRACT In this paper we propose a new line search algorithm that ensures global convergence of the Polak-Ribi ere conjugate gradient method for the unconstrained minimization of nonconvex diierentiable functions. In particular, we show that every limit point produced by the Polak-Ribi ere iteration is a stationary point of the objective function. Moreover, we prove that, asymptotically, the...
