Antimirov's subfactors, in turn, provide a fine-grained analysis of Brzozowski's factors (derivatives), suggesting a smooth path to deterministic finite automata. We believe that this makes a good story line for introducing regular expressions and automata....
The drawback of this construction is that the transition probabilities for mutation heavily depend on the current position. The closer an algorithm gets to 1n, the larger the probability of mutation decreasing the number of ones and moving away from the optimum. We follow a different approach to...
While it's true that Perl's regular expressions resemble the DFAs (deterministic finite automata) of the egrep(1) program, they are in fact implemented as NFAs (non-deterministic finite automata) to allow backtracking and backreferencing. And they aren't POSIX-style either, because those ...
For our subjective assessments, we draw upon a workshop held at the Oxford University Engineering Sciences Department, examining the automata- bility of a wide range of tasks. Our label assignments were based on eyeballing the O∗NET tasks and job description of each occupation. This information...

revalidated across different instructors, schools, and age groups; also the Treasure Hunt activity (covering finite state automata) was examined in a high-school course. Again, no statistically significant differences could be found between CS Unplugged and conventional methods [107]....
