**Subject: Looking for Two Old Papers**

I am looking for two papers connected with the history of barrier

methods for nonlinear optimization problems. The papers are:

K.R. Frisch, "Principles of linear programming - with particular

reference to the double gradient form of the logarithmic potential

method," Memo., Univ. Inst. of Economics, Oslo, 18 October, 1954.

K.R. Frisch, "The logarithmic poitential method of convex

programming," Memo., Univ. Inst. of Economics, Oslo, 13 May, 1955.

I would be most grateful if anyone could send me copies of these, or tell

me where I might obtain them.

I have recently returned from Nigeria where in spite of the tricky

political situation Prof Simeon Fatunla is managing to continue both

research and publication activities. I brought back a stock of copies of

two volumes edited by him

SCIENTIFIC COMPUTING - Proceedings of the 5th International Conference

held at University of Benin January 1992. Ada+Jane Press Nigeria Ltd,

I am undertaking to sell them on his behalf. Proceeds will give valuable

hard currency to put towards running the next conference in 1996. I hope

many na-netters will either order a personal copy or check with their

departmental or central library and if it does not have copies, persuade it

to buy them. Price 18 pounds sterling for the first and 24 pounds for the

second. Includes p&p for mail within Europe, please add 2 pounds for mail

outside Europe. Orders by e-mail to me at na.pryce

(pryce@rmcs.cranfield.ac.uk) or by post to Dr J D Pryce, Software

Engineering Group, RMCS, Shrivenham, Swindon SN6 8LA, UK. Payment by

sterling cheque please.
