Consider an HMM with hidden states X1:t and observed states or evidence variables E1:t. Consider the problem of finding the most likely sequence of states in the HMM, i.e., the sequence X1:t which maximizes P(X1:t |E1:t ).

(a) Describe an algorithm to find the most likely sequence X1:t given an observation sequence E1:t. You have to clearly describe the key variables, equation(s) and computation involved, and discuss the time complexity of the algorithm. You do not have to prove correctness of the algorithm.
