WebThis study is aimed at developing a machine learning algorithm used in solving TSP and compare the solution exact method in order to determine the optimal gap . To achieving this, we set the following objectives: (i) Develop a mathematical formulation for TSP, (ii) Develop a machine learning algorithm for solving TSP, WebNov 15, 2024 · Q-learning uses Temporal Differences(TD) to estimate the value of Q*(s,a). Temporal difference is an agent learning from an environment through episodes with no prior knowledge of the environment. The agent maintains a table of Q[S, A], where S is the set of states and A is the set of actions. Q[s, a] represents its current estimate of Q*(s,a ...
