Abstract
(English)
Additive AND/OR graphs are defined as AND/OR graphs without circuits, which can be considered as folded AND/OR trees; i.e. the cost of a common subproblem occurs, but it is computed only once. Additive AND/OR graphs are naturally obtained by reinterpreting the dynamic programming method in the light of the problem- reduction approach. An example of this reduction is given.
