Venkat Chakaravarthy (UW-Madison): Context Sensitive String Matching

In this talk, we will discuss about context sensitive string matching and related problems. Given a pattern (a string of variables and constants) and a text (a string of constants), the problem is to check if the pattern can be matched with the text by uniformly substituting each variable with a string of constants. We shall discuss the complexity of this problem and its weighted version. We will also look at some related problems such as unavoidability testing and checking the equivalence/inclusion among patterns.
