Abstract

See full text

Embodiments relate to dynamic programming. An aspect includes representing a dynamic programming problem as a matrix of cells, each cell representing an intermediate score to be calculated. Another aspect includes providing a mapping assigning cells of the matrix to elements of a result container data structure, and storing cells of the matrix to elements of the result container data structure in accordance with the mapping. Another aspect includes calculating intermediate scores of all cells of the matrix, whereby intermediate scores of some of the cells of the matrix are stored to a respectively assigned element of the result container data structure in accordance with the mapping. Another aspect includes during the calculation of the intermediate scores, dynamically updating the assignment of cells and elements in the mapping and assembling a final result of the dynamic programming problem from the intermediate scores stored in the result container data structure.
