Finding thek smallest spanning trees

  • David Eppstein
Algorithm Theory


We give improved solutions for the problem of generating thek smallest spanning trees in a graph and in the plane. Our algorithm for general graphs takes timeO(m logβ(m, n)=k2); for planar graphs this bound can be improved toO(n+k2). We also show that thek best spanning trees for a set of points in the plane can be computed in timeO(min(k2n+n logn,k2+kn log(n/k))). Thek best orthogonal spanning trees in the plane can be found in timeO(n logn+kn log log(n/k)+k2).
