Each state of the Markov process is a pair (s,i) where s is the size of the inventory and i is the state of the world (normal or disrupted). While the Rocks problem does not appear to be related to bioinfor-matics, the algorithm that we described is a computational twin of a popu-lar alignment algorithm for sequence comparison. A thief is going to steal the maximal value in these houses, but he cannot steal in two adjacent houses because the owner of a stolen house will tell his two neighbors on the left and right side. Numpy coding: matrix and vector operations. viii + 136 pp. Each of the subproblem solutions is indexed in some way, typically based on the values of its input parameters, so as to facilitate its lookup. Dynamic Time Warping (DTW) in Python Although it's not really used anymore, Dynamic Time Warping (DTW) is a nice introduction to the key concept of Dynamic Programming.
