Eric Vigoda, Computational phase transition and MCMC algorithms
Room B332 IBS (기초과학연구원)This talk will highlight recent results establishing a beautiful computational phase transition for approximate counting/sampling in (binary) undirected graphical models (such as the Ising model or on weighted independent sets). The computational problem is to …

Jinyoung Park (박진영), Thresholds 1/2
Room B332 IBS (기초과학연구원)Thresholds for increasing properties of random structures are a central concern in probabilistic combinatorics and related areas. In 2006, Kahn and Kalai conjectured that for any nontrivial increasing property on …

Seunghun Lee (이승훈), Inscribable order types
Room B332 IBS (기초과학연구원)We call an order type inscribable if it is realized by a point configuration where all extreme points are all on a circle. In this talk, we investigate inscribability of …
Eun Jung Kim (김은정), Directed flow-augmentation
Room B332 IBS (기초과학연구원)We show a flow-augmentation algorithm in directed graphs: There exists a polynomial-time algorithm that, given a directed graph G, two integers
Noleen Köhler, Testing first-order definable properties on bounded degree graphs
Room B332 IBS (기초과학연구원)Property testers are probabilistic algorithms aiming to solve a decision problem efficiently in the context of big-data. A property tester for a property P has to decide (with high probability …
Raul Lopes, Temporal Menger and related problems
Room B332 IBS (기초과학연구원)A temporal graph is a graph whose edges are available only at specific times. In this scenario, the only valid walks are the ones traversing adjacent edges respecting their availability, …
