Different approximate matchers impose different constraints. Some matchers use a single global unweighted cost, that is, the total number of primitive operations necessary to convert the match to the pattern. For example, if the pattern is coil, foil differs by one substitution, coils by one insertion, oil by one deletion, and foal by two ...
A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
The pgrep utility, for instance, displays the processes whose names match a given regular expression. [15] In the Perl programming language, grep is a built-in function that finds elements in a list that satisfy a certain property. [16] This higher-order function is typically named filter or where in other languages.
As fires devastate Los Angeles — displacing people, and burning homes and business — events and premieres continue to be canceled. On Thursday, Apple TV+ canceled its planned premiere for ...

President-elect Donald Trump promised mass deportation on the campaign trail, and while the scale of it remains vague, the elements of the plan are an unlikely call back to former President Barack ...
For example, one might wish to find all occurrences of a "word" despite it having alternate spellings, prefixes or suffixes, etc. Another more complex type of search is regular expression searching, where the user constructs a pattern of characters or other symbols, and any match to the pattern should fulfill the search. For example, to catch ...
