摘要:This article gives an overview of the recent developments in the study of the operations of insertion and deletion. It presents the origin of these operations, their formal definition and a series of results concerning language properties, decidability and computational completeness of families of languages generated by insertion-deletion systems and their extensions with the graph-control. The basic proof methods are presented and the proofs for the most important results are sketched.
