abstract = "The incremental Badoiu-Clarkson algorithm finds the smallest ball
enclosing n point in d dimensions with at least O(1/t^0.5)
precision, after t iteration steps. The extremely simple
incremental step of the algorithm makes it very attractive both
for theoreticians and practitioners. A simplified proof for this
convergence is given. This proof allows to show that the precision
increases, in fact, even as O(u/t) with the number of iteration
steps. Computer experiments, but not yet a proof, suggest that the
u, which depends only on the data instance, is actually bounded by
min{(2d)^0.5,(2n)^0.5}. If it holds, then the algorithm finds the
smallest enclosing ball with epsilon precision in at most O(nd
(d')^0.5 }/epsilon) time, with d=min{d,n}.",
