Return the set of atomic proposition used to build formulae.
| std::ostream& spot::random_formula::dump_priorities | ( | std::ostream & | os | ) | const |
Print the priorities of each operator, constants, and atomic propositions.
| formula spot::random_formula::generate | ( | int | n | ) | const |
Generate a formula of size n.
It is possible to obtain formulae that are smaller than n, because some simple simplifications are performed by the AST. (For instance the formula a | a is automatically reduced to a by spot::multop.)
| const char* spot::random_formula::parse_options | ( | char * | options | ) |
Update the priorities used to generate the formulae.
options should be comma-separated list of KEY=VALUE assignments, using keys from the above list. For instance "xor=0, F=3" will prevent xor from being used, and will raise the relative probability of occurrences of the F operator.
