Space and Time Efficient Structural Improvements of Dynamic Programming Algorithms Jesper Nederlof The subject of this talk is a NWO-project studying the Dynamic Programming paradigm. The main question here is to perform the following task as efficient as possible, in terms of space and time: Given a recurrence, determine one of its specific values. We will first survey a number of previous results. Most importantly, by applying transformations, for many recurrences the above task can be performed in space-efficient manner. This is in strong contrast with more naive methods where all values of the recurrence need to be stored. Then we will discuss further research directions on this subject. The talk will be self-contained, but familiarity with dynamic programming and standard NP-complete problems will be helpful to fully appreciate the talk.
