Download Reachability Problems

Each participating team is invited to briefly present their approach to the RERS benchmarks at the corresponding event.

Note that these problems cannot be compiled as downloaded because of a missing implementation of the __VERIFIER_error(int). Please read the Java-code and C99-code description for compilation assistance. Other useful information can be found on the problem description page. Training problems are available and feature corresponding solutions.


The problems are provided as a .zip archive.
