**Subject: Monte Carlo Speedup**

It is being told that the best way to achieve perfect speedup of Monte Carlo

simulations is to simply do as many runs as there are processors. This sounds

like a half truth because if the two runs use the same random numbers there is

no speedup at all.

Are there known results that quantify speedup as a function of statistical

independence among random number streams?

Would you know of any real-life example where incorrect conclusions were drawn

from Monte Carlo because of invalid assumptions about the sequence of random

numbers?

With best regards,

**Subject: Spectral Projectors for Matrix Polynomials**

Dear NA readers,

The spectral projector for a linear matrix polynomial (i.e.,

generalized) is

P_\Gamma(A,B) = \frac{1}{2\pi i} \oint\limits_\Gamma (\lambda B-A)^{-1}

B d\lambda

for A x = \lambda B x. Is it possible to find a similar expression for

quadratic matrix polynomials (A + \lambda B + \lambda^2 C)x = 0 ?

It is well known, that a matrix polynomial can be reduced to a (large)

generalized problem, but

is there any other possibility with respect to the representation of the

spectral projector ?

Does anyone know of any references for this problem ?

**Subject: GMM++, A Generic C++ Matrix Library**

GMM++ 1.5 Available for Download

This generic matrix library is built as an interface for already existing

class of vectors and matrices. It provides also predefined type of dense,

skyline and sparse matrices. It is largely inspired from MTL/ITL but we hope

a little bit simpler to use. matrix x matrix multiplication works for any

type of matrices (even with mixed types).

An important extension is the possibility to access to sub-matrices for read

or write operations with any kind of interfaced matrix.

Linear solvers has been imported from ITL (CG, BICGSTAB, GMRES, QMR, dense

LU, ...) with classical preconditionners (Incomplete cholesky, ILU, ILUT ...)

The performance is comparable with the one of MTL, slightly better on some

solvers we optimized.

Inpout / output with standard formats is also provided.

This library is available under LGPL licenseand may be downloaded at:

A short documentation exists.

New From CRC Press

A Numerical Library in JAVA for Scientists and Engineers by Hang T. Lau

This groundbreaking handbook represents the only inexpensive numerical library

available for the use of JAVA in scientific computation. It provides a library

of Java-based procedures that perform fundamental mathematical computations

critical to researchers. It includes procedural descriptions of linear algebra,

the numerical solutions of ordinary and partial differential equations,

optimization, parameter estimation, and special functions of mathematical

physics. The handbook also enables the user to experiment with the many JAVA

procedures provided in order to observe computational success and simulate

failure.

**Subject: New Book, Reinforcement Learning and Simulation Optimization**

Colleagues and Friends:

Kluwer Academic has recently published a new book on simulation-based

optimization and reinforcement learning.

More information about the book can be found at the following website.

http://www.eng.buffalo.edu/~agosavi/book.html

Here is a brief description of the book's contents.

SIMULATION-BASED OPTIMIZATION: PARAMETRIC OPTIMIZATION TECHNIQUES AND

REINFORCEMENT LEARNING

This book provides a unified treatment to static and dynamic models of

simulation-based optimization. It aims at providing an introduction to

exciting developments in the theory of simulation-based optimization in an

accessible format. The book divides the field of simulation-based

optimization into two parts: static and dynamic optimization. The methods

discussed for dynamic optimization are primarily Reinforcement Learning and

Learning Automata, while those for static optimization are Simultaneous

Perturbation and Meta-heuristics.

PhD Student in Numerical Mathematics/Scientific Computing

on the project "Mesoscale simulation paradigms in the Silicon Cell".

The research topic is the development of numerical methods and software for

an adaptive grid method for reaction-diffusion PDE systems with irregular,

dynamically changing, interfaces. The aim of the project is to compare this

continuum approach with a particle-based method (Lattice Boltzmann, developed

by a second PhD student) for problems with large spatial and temporal scales

such as arise, e.g., in the study of biological cells.

Profile:

Candidates should have an MSc in (numerical) mathematics, scientific

computing or computational science, (computational) physics, computational

fluid dynamics, or a comparable expertise. Candidates are also expected to

have an active interest in life science applications.

Application:

Please send your application to the

Personnel Department CWI,

P.O. Box 94079,
