Why is compression a "hard problem" for computers? draw on your own experience compressing text with the text compression widget. is there a way to know when you've compressed it the most? explain why you can or can't know.?

Compression is hard since we usually find it difficult to determine the best compression rate .

When using the text compression widget we make a key that represent every work we have repeated in order to decrease the stored data.

When you have extends you compression beyond what it should be it is easy to notice since there will be no algorithm and that makes it hard hence we end up making assumptions on what ratio we will use for compression by using a thorough key.
