In formal languguage theory, regularity is a robust notion having many equivalent representations: regular expressions, ï¬nite state automata, MSO etc. These have made important impact on programming and veriï¬cation tools.

Algorithms working on large data(say of size n) should be both space and time efficient. Any algorithm has to see atleast the whole data once, so time required has to be atleast n(see sublinear time algorithms for exceptions).
