Foreword: programming language interference and dependence

Interference and dependence are closely related concepts, the first being the observable phenomenon connected to the second. Interference essentially means that behavior of some parts of a dynamic system may influence the behavior of other parts of the same system. Dependence instead specifies the relation between the semantics of sub-components of a dynamic system. Discovering, measuring and c...

Foreword: special issue on mathematical programming in biology and medicine

In recent years, mathematical programming and optimization techniques have been increasingly applied to various fields of biological and medical sciences, and in many cases have become indispensable tools. This volume contains a collection of five papers in this area. In this foreword, we aim to provide a little context for the applications described in these papers and, in particular, their us...

A Foreword to 'Fundamental Concepts in Programming Languages'

Christopher Strachey’s paper on Fundamental Concepts in Programming Languages is being published here for the first time. Written in the autumn of 1967, it is based on the lectures given by Strachey at an International School in Computer Programming, held in Copenhagen in August 1967. Strachey intended the paper to be published in the proceedings of the School—but the proceedings never material...

Foreword: for Special Issue on Semide nite Programming

Semideenite programming (denoted SDP) is an extension of linear programming (LP), with vector variables replaced by matrix variables and nonnegativity elementwise replaced by positive semideeniteness. Let us express a (primal) SDP as min C X s.t. AX = b X 0; where: C; X are in S n , the space of symmetric n n matrices; the inner product C X = trace CX; denotes nonnegativity in the LL owner part...
