Abstract

We examine the state complexity of proportional removals such as ½(L). For ½(L), we show a bound which is tight in the case that L is a unary language, and an nearly optimal bound for arbitrary languages. We also compute the average state complexity for ½(L) if L is unary. We study other proportional removals and give bounds for certain reset automata.
