SUMMARY:Graphs and Matroids - Sophie Spirkl
CLASS:PUBLIC
DESCRIPTION:TITLE: Odd cycle transversal in P5-free graphs\n\nSPEAKER:\n So
 phie Spirkl\n\nAFFILIATION:\n University of Waterloo\n\nLOCATION:\n MC 541
 7\n\nABSTRACT: Odd cycle transversal is a fun computational problem\,\nsom
 ewhere between colouring and independent set: we are (equivalently)\nlooki
 ng for a bipartite induced subgraph of maximum weight. As one\nmight expec
 t\, this is NP-hard\; I will tell you how to solve this\nproblem in polyno
 mial time in P5-free graphs (and more). Joint work\nwith Cece Henderson\, 
 Evelyne Smith-Roberge\, and Rebecca Whitman. \n\nNote: I am COVID-cautious
  and will bring masks for those willing to\nwear them. \n\n
