The main result of this paper is an algorithm for approximate matching of a regular expression of size \(m\) in a text of size \(n\) in time \(O\left(n m / \log _{d+2} n\right)\), where \(d\) is the number of allowed errors. This algorithm is the first \(o(m n)\) algorithm for approximate matching t
