Subject: Peter Wynn (1932-2017)

I regret to inform you of the passing of Peter Wynn from a heart
attack in December 2017.  He was living in Zacatecas, Mexico.  Peter
was born in 1932. He first studied with Arthur Erd\'elyi.  Then he
defended a Thesis in 1959 at the Johannes Gutenberg-Universit\"at in
Mainz under the supervision of Friedrich L. Bauer and he became his
assistant. Then, he went to Amsterdam, participating in the birth of
ALGOL. In 1961, he obtained a Ph.D. from the University of London.  He
found his famous epsilon-algorithm for the recursive implementation of
Shanks' transformation in 1956 when he was only 24. He held several
positions in the United States, Canada and Mexico. He published 105
Research Reports and papers on convergence acceleration, Pad\'e
approximation and continued fractions.

Without him the field of extrapolation methods would not have
been so much developed.

Subject: CNRS Silver Medal for Pierre Comon

Pierre Comon has won the 2018 CNRS Silver Medal for Information
Sciences and Technologies. The medal honors researchers who are
recognized nationally and internationally for the originality,
quality, and importance of their work:
http://www.cnrs.fr/en/research/awards/silvermedals.htm

The official laudatio (translated from French) reads: "Pierre Comon,
CNRS Research Director at Gipsa-Lab (Grenoble Image, Speech, Signal,
and Automatic Control) of the University Grenoble-Alpes, is the winner
of the 2018 Silver Medal of the CNRS Institute of Information Sciences
and Technologies (INS2I). This medal recognizes the excellence and
impact of his works. His research works focus on models that are

Subject: Re: A linear algebra query

I asked in the 25 March issue: How do you tell in O(n^2) time whether
a real n by n matrix Q, known to be orthogonal, has determinant +1 or -1?

After a few replies that don't work, I begin to think it is
impossible. Of course this depends on the methods that are allowed.

Assuming one is allowed ordinary matrix operations:
- Size n matrix-matrix multiplication is not allowed as it's O(n^3).
- To remain O(n^2), one can have up to M matrix-vector multiplications
  where M is some universal bound independent of n.

Equivalently, you are allowed to know the action of Q on some
M-dimensional subspace X. But I think as soon as n exceeds M, Q is
determined by its action on X (known) and on the nontrivial orthogonal
complement Xperp (totally unknown). And (I've not checked details but
it seems clear) one can always define a different action on Xperp that
reverses the orientation.

I find this strange but convincing. Can anyone show it is wrong?

Subject: Open-source GALAHAD 3.0 for nonlinear optimization is now available

GALAHAD is an evolving library of modern Fortran packages for
nonlinear optimization. It contains packages for general constrained
and unconstrained optimization, quadratic programming, and nonlinear
least-squares fitting, as well as those for solving a large variety of
basic optimization subproblems. Many of the packages can be called
from Matlab. We are pleased to announce that from Version 3.0, the
library is freely available as open-source software released under the
LGPL.

For download details and installation instructions, visit
  https://github.com/ralna/GALAHAD/wiki

GALAHAD is available as part of the Optimization Trove
  https://github.com/ralna/optrove/wiki
alongside CUTEst, RALFit and a variety of optimization test examples.
