Arjen Lenstra wrote LIP, a long integer package, which formed the basis of NTL. Keith Briggs developed a quadratic precision package. NTL has incorporated parts of these two packages, although what is in NTL has been extensively re-written. Thanks also to Keith for many helpful comments and suggestions. <li> Thanks to <a href="http://www.juergen-gerhard.net">Juergen Gerhard</a> for pointing out the deficiency in the NTL-1.0 ZZX arithmetic, for contributing the Schoenhage/Strassen code to NTL 1.5, and for helping to track down some bugs. <li> Thanks to <a href="http://www.di.ens.fr/~pnguyen">Phong Nguyen</a> for putting the new LLL code (NTL 1.7) through a torture test of lattices arising from new lattice-based cryptosystems; this led to a number of significant improvements in the LLL code. <li> Thanks to <a href="http://theory.stanford.edu/~dabo">Dan Boneh</a> for encouraging me to improve NTL's programming interface. <li> Thanks to John Abbott, <a href="http://www.math.fsu.edu/~hoeij">Mark van Hoeij</a>, and <a href="http://www.loria.fr/~zimmerma">Paul Zimmermann</a> for sharing many of their ideas about polynomial factoring over <tt>ZZ</tt> with me, which led to a number of improvements in NTL's factorizer. Thanks also to Paul for numerous other suggestions and improvements. <li> Thanks to <a href="http://math-www.uni-paderborn.de/~aggathen/joachim.html">Joachim von zur Gathen</a> and <a href="http://www4.ncsu.edu/~kaltofen">Erich Kaltofen</a> for their collaboration and support over the years. </ul> </body> </html>
