A survey of applications of factorization forests. Fix a regular language L ⊆ A∗. You are given a word a1 · · · an ∈ A∗. You are allowed to build a data structure in time O(n). Then, you should be able to quickly answer queries of the form: given i ≤ j ∈ {1, . . . , n}, does the infix ai · · · aj belong to L? What should the data structure be? What does quickly mean? There is natural solution that uses a divide and conquer approach. Suppose that the language L is recognized by a… CONTINUE READING
