Subject: Oops, Two Issues Numbered 5

We've recently switched the NA Net source machine at Stanford
from "score", an old DEC 10 or 20 running TOPS, to "na-net",
a Sun running UNIX. (Thanks to Mark Kent for making the
switch.) In the process, I forget to increment the issue
number, so there have been two issues numbered 5. I'm calling
this issue number 7 in case anybody else is saving back issues
and wants room to call one of those issue number 6.

Subject: Polynomial Zeros in C

I am looking for a good algorithm for computing all the
rational zeros of a polynomial with real coefficients. The
polynomial power, the value of each coefficient and the
absolute value of the acceptable error are given by the user.
Initial information about the zeros is not available.

The highest power is 127 and the maximum error is 10exp(-15).
The program will be written in C and it is assumed that the
target machines have a 64-bit double float including 10+1 bits
for the exponant and 52+1 bits for the mantissa and that
correct rounding is used.

If you can help me please let me know via any mean you see fit.

Thanks in advance.

Subject: Numerical Analysis Position at Johns Hopkins University





The Department of Mathematical Sciences at Johns Hopkins has an open tenure-
track junior position in numerical analysis/optimization. Recruiting is now
underway, so anyone interested should communicate with us right away. Direct
inquiries from prospective candidates are welcome, as are referrals from third
parties. For rapid response to informal inquiries contact Roger Horn at
that the underscore is essential). To apply formally, write to Professor
Robert Serfling, Chairman.

Subject: Special Issue of Mathematical Programming


A special issue of Mathematical Programming Series B devoted
to large scale problems is being prepared under the joint editorship of
A.R.Conn, N.I.M.Gould and Ph.L.Toint..

The emphasis is intended to be towards large scale nonlinear programming
rather than linear programming. However, articles that emphasize applications,
algorithms and/or theory that is not primarily linear programming oriented
could be suitable and are solicited.

Mathematical Programming Series B is now on a similar schedule to Series A
with similar standards for publication and the same circulation.

The advantage of a special issue, besides collecting articles on a coherent
theme is that the refereeing process can often be expedited.

If you have a suitable paper for such an issue you are invited to submit
it to one of the editors

The deadline for submission is August 1 1988 for the issue that is to be
published in 1989.
Late submissions, an excess of submissions, etc., would automatically be
considered for Mathematical Programming Series A, unless the author wishes

Subject: MILP/MINLP Software

I am looking for software packages to numerically solve MILP (Mixed Integer
Linear Programming) and MINLP (Mixed Integer Non Linear Programming)
optimization problems.

I would appreciate it if you could tell me what are the available
packages and how I could lay my hands on them.
