Solving Parallel Equations with BALM-II

In this report we describe how to solve parallel language equations over regular languages / automata and finite state machines (FSMs), using the software package BALM-II. The original version of BALM could solve equations only with respect to synchronous composition; we extended the original code to solve also equations with respect to parallel composition, adding new commands and procedures. The new version of BALM is called BALM-II, of which this document provides a user's manual. Finally, as an important application, we describe how to synthesize protocol converters with BALM-II
