The Oberwolfach problem (OP) asks whether Kn (for n odd) or Kn minus a 1-factor (for n even) admits a 2-factorization where each 2-factor is isomorphic to a given 2-factor F . The order n and the type of the 2-factor F are the parameters of the problem. For n ≤ 17, the existence of a solution has been resolved for all possible parameters. There are also… (More)

models [7,8,13] to study linear optimization has recently achieved the exciting result of a subexponential lower bound for Zadeh’s rule [8], another long-standing open problem. On the positive side, several authors have recently shown upper bounds for interesting special cases of the simplex method [21] and the diameter problem [5]. In this article, we show… (More)

In 1966, Claude Berge proposed the following sorting problem. Given a string of n alternating white and black pegs on a one-dimensional board consisting of an unlimited number of empty holes, rearrange the pegs into a string consisting of ⌈n 2 ⌉ white pegs followed immediately by ⌊n 2 ⌋ black pegs (or vice versa) using only moves which take 2 adjacent pegs… (More)

The Clinical Psychology Training Program (CPTP) offers a two-year fellowship comprised of a one-year general clinical psychology internship (APA-accredited) and a one-year postdoctoral clinical and clinical research fellowship, based on the scientist-practitioner model. Graduates are expected to pursue careers emphasizing research and training in… (More)

Let ∆(d, n) be the maximum possible diameter of the vertex-edge graph over all d-dimensional polytopes defined by n inequalities. The Hirsch bound holds for particular n and d if ∆(d, n) ≤ n − d. Francisco Santos recently resolved a question open for more than five decades by showing that ∆(d, 2d) = d + 1 for d = 43; the dimension was then lowered to 20 by… (More)
