(�� <<11BF2B245F1C0740872D2843AD021A3E>]>> UMF011 – Introduction to bioinformatics, 2005 12 Dynamic programming Dynamic programming (DP) is an efficient recursive method to search through all possible alignments and finding the one with the optimal score. The method was developed by Richard Bellman in the 1950s and has found applications in numerous fields, from aerospace engineering to economics.. Computer science: theory, graphics, AI, systems, …. dynamic programming, Hidden Markov Model (HMM), Regression analysis, Artificial Neural Network (ANN), Clustering and Sequence Mining to analyse the given sequence. The framework of algebraic dynamic programming (ADP) allows us to express dynamic programming algorithms for sequence analysis on a high level of abstraction.
