ddSMT: Delta Debugging for SMT-LIBv2

ddSMT is a delta debugger for input in the SMT-LIB language and its dialects and extensions. It serves as an input minimizer for SMT-LIB(-like) input that triggers interesting behavior for a given command. Noteworthy examples for supported extensions of the SMT-LIB language are the SyGuS input format and the extension for encoding separation logic problems. For more details on the SMT-LIB language, see http://www.smtlib.org.

ddSMT is implemented in Python 3 and developed on a Linux OS.

ddSMT is released under the MIT (see file LICENSE).
