Algorithm 4.2
Randell algorithm. Assuming initial state S
0
has been put into
states set S :
1. stop if S is empty;
2. choose state S
i
from S and remove it;
3. go to step 2 if S
i
is an inconsistent state;
4. apply state constraint and choose usable transition rule;
5. generate next possible states set with selected rules;
6. apply adding and deleting rules;
7. check constraint between states;
8. add the left states to S and go to step 1.
