The table was generated with the
following python functions:
def ProbMinXX(N, i): return (2.0*(N-i)-1)/(N*N)
def ProbMaxXX(N, i): return (2.0*i+1)/(N*N)
def ExpFn(N, ProbFunc):
exp = 0.0
for i in xrange(N): exp += i*ProbFunc(N, i)
return exp
The current choice for second-layer guards is noted with **, and
the current choice for third-layer guards is noted with ***.
