This is an implementation of a custom base encoding algorithm, which allows for the encoding and decoding of text strings using a custom alphabet and base size. The encoding and decoding functions use the standard library string module to define the alphabet, which consists of all uppercase and lowercase letters, digits and punctuation characters. The alphabet size is set to 1052672 characters, but can be modified through the function arguments. The base size is set to 256, but can also be modified through the function arguments. The encoding function takes an input string and converts each character to its corresponding index in the alphabet. It then takes the resulting number and encodes it using the specified base size. The decoding function takes an encoded string and converts it back to the original number by reversing the process of the encoding function. The optimize_baseX function is used to optimize the size of the encoded string by searching for the best combination of alphabet size, base size, alphabet multiplier, and base multiplier. It does this by iterating through all possible combinations and encoding the input string with each one. The encoded string with the smallest length is then chosen as the optimal combination. The function also includes a check for the input string size, and adjusts the alphabet and base size accordingly. If the input string size is smaller than 100, the alphabet and base size are decreased by 50%, and if the input string size is larger than 1000, the alphabet and base size are increased by 50%.
