Description

User sees different results from S+NuOpt when executing code on a different machine.

 

Environment

Product: TIBCO Spotfire S+NuOpt Version: All supported versions OS: All supported versions --------------------

Resolution

You need to make certain that S+NuOpt is loaded using:

module(nuopt, first=T)

so that it is loaded in the appropriate area in the search path.

If this is not done and S+NuOpt is loaded below the stat database, the S+ NuOpt "~" object is masked by the stat "~" object, leading to different (and possibly incorrect) solutions.
