I suspect the best value for eps might be sqrt(DBL_EPSILON), usually 2**-26, roughly 1.6*10**-8 .
If a model requires distinguishing between 1-eps and 1+eps, another model might be in order. Not a lot of generic advice can be given, that said, X >= L1, X>= L2 can always become X>=max(L1, L2). -- Michael henne...@web.cs.ndsu.nodak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards
