SUMMARY:Tutte Colloquium - Bill Cook
CLASS:PUBLIC
DESCRIPTION:TITLE: An approximate solution to a 2\,079\,471-point travelin
 g\nsalesman problem\n\nSpeaker:\n Bill Cook\n\nAffliation:\n University of
  Waterloo\n\nZoom:\n Please email Emma Watson\n\nABSTRACT:\n\nTogether wi
 th Keld Helsguan\, we have found a TSP tour through the 3D\npositions of 2
 \,079\,471 stars. We discuss how linear programming allows\nus to prove th
 e tour is at most a factor of 0.0000074 longer than an\noptimal solution. 
 The talk will focus on the use of minimum cuts and\nGF(2) linear systems\,
  to drive the cutting-plane method towards strong\nLP relaxations.
