First of all, let me give a basic intuition of $DQN$ (Deep Q-Network). It is composed of $D$ (deep learning) and $QN$ (Q-Network), among which the Q-Learning algorithm is the core and the neural network is just a tool to maintain the matrix in Q algorithm because of the memory limits (a $state \times actioin$ size of matrix is too big for most of the times). Algorithm DescriptionQ-LearningIt is explained in detail in this blog: A Painless Q-Learning Tutorial DQNSimilar to dynamic programming, th ...

It’s Time To Learn PYTHON! (record of python challenges)Sometimes refer to the solutions to all the passes: HackingNote Python Challenges Solutions The First PassThe gibberish displayed on the screen is a passcode which is coded with Caeser cipeher, one of the simplest encryption techniques. From the Wikipedia, we can know that It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a l ...
