What is the function of the parameter slots? #19

Is the bit length of the ciphertext? If you increase the slots, does it mean that you can perform more homomorphic operations?THX for your reply！

HEAAN (and other many RLWE homomorphic encryption) uses a batching technique to encrypt a batch of values (e.g. integer or real numbers) into a single ciphertext. So the "slots" denotes the number of values to be encrypted at once, and (basically) there is no connection between the slots and the number of operations you can perform.
