LPNMR'99
5th International Conference on Logic Programming and Nonmonotonic Reasoning

El Paso, Texas USA, December 2-4, 1999


The proceedings are now available online at the Springer site.


LPNMR'99 is the fifth in the series of international meetings on logic programming and nonmonotonic reasoning. Four previous meetings were held in Washington, U.S.A., in 1991, in Lisbon, Portugal, in 1993, in Lexington, U.S.A., in 1995, and in Dagstuhl, Germany, in 1997.

LPNMR'99 will be coordinated with the ICLP'99, which starts on November 29 in Las Cruces, approximately 40 miles from El Paso.

The proceedings of LPNMR'99 will be published by Springer in the LNCS/LNAI series.
