This Java project is an implementation of the algorithm presented in the paper 'Path-ZVA: general, efficient and automated importance sampling for highly reliable Markovian systems' by Daniël Reijsbergen, Pieter-Tjerk de Boer, Werner Scheinhardt, and Sandeep Juneja. This implementation was used to create the tables in the paper - however, the general set-up should make it straightforward to extend the program with different models or importance sampling schemes.See README.txt
