WebTo recap, a hill climbing algorithm is shown below: 1. Generate a random key, called the 'parent', decipher the ciphertext using this key. Rate the fitness of the deciphered text, store the result. 2. Change the key slightly (swap two characters in the key at random), measure the fitness of the deciphered text using the new key.

Link to Python implementation:... WebThe matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible (modulo 26). The cipher can, of course, be adapted to an alphabet with any number of letters; all arithmetic just needs to be done modulo the number of letters instead of modulo 26. The key matrix must be a square matrix. For example:
