Closure under Regular Operations •We started this before and did it for Union only –Union much simpler using NFA •Concatenation and Star much easier using NFA •Since DFAs equivalent to NFAs we can now just use NFAs •Fewer states to keep track of because we can act as if we always “guess”correctly 9/18/20 Theory of Computation
