Explain why L={(ab)^n a^k:n>k,k>=0} is not regular?
asked in Theory of Computation by Active (1.5k points) | 24 views
Because you have the relation between n and k
So if we have a relation between n and k than how can we say that it is Not regular.
if relation exist then you have to compare n and k right?

you need memorization for comparing n and k but FA doesn't have memory, therefore it is not RL
@Shaik, Just little bit modification required.
Here you need infinite memorization (like by using a stack), but in FA we have only states to keep track of past information and FA has finite no. of states. :)
yes mam, it should be updated with your sentence,
