(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. --Cleve ------------------------ >From: Aaron J.

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.

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 NA.HORN@SCORE.STANFORD.EDU or directly through BITNET at MSC_HRAH@JHUVMS (note that the underscore is essential). To apply formally, write to Professor Robert Serfling, Chairman. ------------------------ >From: Andrew Roger Conn <arconn%water.waterloo.edu@RELAY.CS.NET> Date: Thu, 11 Feb 88 22:14:22 EST Subject: Special Issue of Mathematical Programming MATHEMATICAL PROGRAMMING CALL FOR PAPERS 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 A.R.Conn Department of Combinatorics and Optimization Faculty of Mathematics University of Waterloo Waterloo Ontario Canada N2L 3G1 Tel:519-888-4458 E-mail: arconn@water.bitnet arconn@water.waterloo.edu N.I.M.Gould Computer Science and Systems Division A.E.R.E.

Late submissions, an excess of submissions, etc., would automatically be considered for Mathematical Programming Series A, unless the author wishes otherwise. ------------------------ >From: Gene Golub <golub@golubsun.cs.umd.edu> Date: Mon, 8 Feb 88 13:34:54 EST Subject: Congratulations Alan George Alan George will be leaving UTK/ORNL to assume the position of Provst and Vice-President at the University of Waterloo effective July 1, 1988. --Gene ------------------------ >From: Margaret Wright <OR.WRIGHT@Sierra.Stanford.EDU> Date: Fri 12 Feb 88 11:21:34-PST Subject: New Address for Margaret Wright As of February 15, 1988, my address, phone and e-mail address will be: Margaret H.
