SSJ release highlights

SSJ 3.3.0

This release contains new packages, several new classes, an improved tutorial and improved documentation in general.

  • new packages: mcqmctools, latnetbuilder, stat.density, discrepancy.
  • several methods have been added in many places.
  • the main API page (introduction), the tutorial (with examples), and the documentation of several packages have been updated.

SSJ 3.2.1

This release contains bug fixes.

  • package functionfit: Fix bug when creating an approximate BSpline.
  • package util: bisection and brentDekker methods will now check the bounds of the interval first.

SSJ 3.0.0-rc1

This version of SSJ is not for production.

We have just migrated the source code from a custom documentation system which generated Java files from LaTeX input files. Now the Java source code is readily editable. The documentation is in now Doxygen format, which supports mathematical formulas and BibTeX citations.

Users of SSJ 2.6 who want to upgrade their code for SSJ 3 need to replace umontreal.iro.lecuyer with umontreal.ssj in the package imports. For example,

import umontreal.iro.lecuyer.rng.MRG32k3a; // using SSJ 2

becomes

import umontreal.ssj.rng.MRG32k3a; // using SSJ 3
