چکیده
Recall that one of the most commonly used reductions is the L-reduction, introduced by Papadim itriou and Yannakakis in [?]. This reduction consists of a pair of polynomial mappings (f(.), g(.)) where f maps an instance x of the problem A we are reducing from to an instance x/ of the problem B we are reducing to, and g maps a feasible solution y/ (of x/ i.e. instance of B) to a feasible solution y (of x) such that the following conditions hold:

Algorithmic Lower Bounds : Fun With Hardness Proofs Fall 2014 Lecture 3 Scribe Notes
Last time, we established the hardness of two fundamental problems, (2-)Partition and 3-Partition, and exhibited a bunch of reductions from those problems to other numerical and geometrical ones. Today, we continue with reductions from 3and 2-Partition to geometrical problems—we’ll also use the fact that the problem of packing n squares into a square without rotations is strongly NP-complete, a...

In the previous lecture, we looked at the APSP problem and some of the other closely related problems. We studied the cubic hardness of these problems. In this lecture, we will go about doing something similar, but in the domain of quadratic hardness. With regard to this, we will choose 3-SUM problem as the representative problem. We will look at some related problems, that can be reduced to th...

In the next two lectures, we look at lower bounds conjectured on two important and well-known problems. One is the All-Pairs-Shortest-Path(APSP) problem which is believed to be truly cubic(i.e. there is no exact algorithm for this problem which runs in time O(n ) for a constant > 0). The second problem considered is the 3−SUM problem which is conjectured to be truly quadratic(i.e. there is no e...

In the previous lectures, we looked at the online algorithms and studies some of the related problems. Now we look into streaming algorithms, which have many similarities with online algorithm. They both require decisions before seeing all data but streaming algorithms can defer actions with limited memory. In these two lectures, we introduce streaming algorithms, related communication complexi...
متن کاملCS 49 : Data Stream Algorithms Lecture Notes , Fall 2011 Amit
Acknowledgements These lecture notes began as rough scribe notes for a Fall 2009 offering of the course " Data Stream Algorithms " at Dartmouth College. The initial scribe notes were prepared mostly by students enrolled in the course in 2009. Subsequently, during a Fall 2011 offering of the course, I edited the notes heavily, bringing them into presentable form, with the aim being to create a r...
