1998 Nonlinear Programming Software Survey The information in this survey was provided by the vendors in response to a questionnaire developed by Stephen Nash. The survey should not be considered as comprehensive, but rather as a representation of available NLP packages. The listings are limited to products that fit the parameters of the survey as outlined in the accompanying article. Questionnaires were sent to 45 vendors drawn from previous survey participants, the OR/MS Today database and other sources. It includes the products of those vendors who responded by March 31. If you know of an NLP package that is not in the survey, please contact Patton McGinley at (770) 431-0867, ext. 214 or e-mail patton@lionhrtpub.com. It will be included in an online version.
