2003-07-18 Heikki Tauriainen <heikki.tauriainen@hut.fi>
* UserCommands.cc (printAutomatonAnalysisResults): Ensure that
the states in a witness for the nonemptiness of two Bûchi
automata are distinct to prevent the truth valuation for the
atomic propositions from being defined multiple times in any
state of the witness.
* Version 1.0.2 released.
2003-07-17 Heikki Tauriainen <heikki.tauriainen@hut.fi>
* NeverClaimAutomaton.cc (ParseErrorException::ParseErrorException):
Fix a string buffer overflow.
* ProductAutomaton.cc (findAcceptingExecution): Concatenate
fragments of an accepting cycle in the correct order. (Thanks to
Joachim Klein for pointing out an example uncovering the bug
in previous releases.)
2002-11-04 Heikki Tauriainen <heikki.tauriainen@hut.fi>
* StatDisplay.cc (printCollectiveStats): If using more than five
formula operators (but the total number of operators is not
a multiple of 5), insert an empty line in the output before the
last row of the operator distribution table.
