Lecture 7 - Dynamic Trees Lecturer : Michel
1 Overview In this lecture, we discuss dynamic trees, a sophisticated data structure introduced by Sleator and Tarjan. Dynamic trees allow to provide the fastest worst-case running times for many network flow algorithms. In particular, it will allow us to efficiently perform the Cancel operation in the Cancel and Tighten algorithm. Dynamic trees build upon splay trees, which we introduced in th...
متن کاملMichel X . Goemans 7 . Lecture notes on the ellipsoid algorithm
The simplex algorithm was the first algorithm proposed for linear programming, and although the algorithm is quite fast in practice, no variant of it is known to be polynomial time. The Ellipsoid algorithm is the first polynomial-time algorithm discovered for linear programming. The Ellipsoid algorithm was proposed by the Russian mathematician Shor in 1977 for general convex optimization proble...

We now consider some examples of jump systems. Example 1. Let M be a matroid over a set S, |S| = n. We let each coordinate of Z correspond to an element of S, and let J ⊆ {0, 1}n be the set of characteristic functions for bases of M , J = {χB|B a basis of M}. Claim 1. The set J is a jump system. Proof. Let x and y be the respective characteristic vectors of two bases b1 and b2 of M . A step x f...

We study differential-geometrical structure of an information manifold equipped with a divergence function.A divergence function generates a Riemannian metric and furthermore it provides a symmetric third-order tensor,when the divergence is asymmetric. This induces a pair of affine connections dually coupled to each other withrespect to the Riemannian metric. This is the arising eme...
متن کاملMichel Labouesse
Michel Labouesse grew up near Paris. He studied maths and physics for a degree in engineering, but subsequently embraced a career in biology. He learned genetics during his PhD with Piotr Slonimski in Gif/Yvette, where he analysed how the nuclear genome controls expression of mitochondrial genes in yeast. He then went on to learn developmental biology of the nematode Caenorhabditis elegans as a...
