Details of the hypergraph:
Center node: "exact algorithms for maximum independent set"
  Abstract: Abstract   We show that the maximum independent set problem on an n-vertex graph can be solved in      1.1996    n      n    O  (  1  )      time and polynomial space, which even is faster than Robson's      1.2109    n      n    O  (  1  )     -time exponential-space algorithm published in 1986. We also obtain improved algorithms for MIS in graphs with maximum degree 6 and 7, which run in time of      1.1893    n      n    O  (  1  )      and      1.1970    n      n    O  (  1  )     , respectively. Our algorithms are obtained by using fast algorithms for MIS in low-degree graphs in a hierarchical way and making a careful analysis on the structure of bounded-degree graphs.
