Spanning Tree Protocol in a nutshell.

Best way to memorize decidability table. Regular: Decidable everywhere CFL: Decidable only for, MEMBERSHIP, FINITENESS, EMPTINESS CSL: Decidable only for, MEMBERSHIP REC: Decidable only for, MEMBERSHIP RE: Nowhere Decidable

Best way to memorize the closure properties: No language is closed under : Subset, Superset, Infinite union, Infinite intersection and infinite set difference. Regular languages are closed under in all the other operations. DCFLS are NOT closed under most of the operations EXCEPT : Complementation and Inverse Homeomorphism. CFL: Closed under all except, INTERSECTION and COMPLEMENT CSL: Closed under all basic operations REC: Same as CSL RE : Same as CSL except NOT closed under COMPLEMENT NOTE: All languages are closed under UNION, INTERSECTION and SET DIFFERENCE with Regular Sets.
