"If I had more time, I would have written a shorter letter" is a quote from French mathematician and philosopher Blaise Pascal in his 1657 Lettres Provinciales. Summarize your reflection paper in a 50- to 60-word abstract. Describe the differences between the computational complexity of classes P and NP. What is the Halting Problem? If the Halting Problem were solvable, describe in detail the technological and societal implications. All six (6) of the following statements are false. Choose three (3) of the six (6) statements below and show that they are false by either using a counterexample, or citing a theorem or an established fact. For example, both O and (e) are known to be context free. 1. If L₁ is context free and L2 is not context free, then L₁ L2 is NOT context free. 2. If L₁ is context free and L₂ is not context free, then L₁ L₂ is context free. 3. Every context free language is not regular. 4. If L₁ is context free and L₂ is not context free, then L₁ L₂ is NOT context free. 5. A non-deterministic Turing Machine can decide languages that standard Turing Machine cannot decide. 6. There are languages that are decided by a Turing Machine with two (2) tapes, but is undecidable by a Turing Machine with one (1) tape. For the following Turing Machine carry out the computations, starting with configuration (s, Duabu). (Note: R2 means R₁R).
