Comparing Imperfection Ratio and Imperfection Index for Graph Classes
Perfect graphs constitute a well-studied graph class with a rich structure, reflected by many characterizations with respect to different concepts. Perfect graphs are, for instance, precisely those graphs G where the stable set polytope STAB(G) coincides with the fractional stable set polytope QSTAB(G). For all imperfect graphs G it holds that STAB(G) ⊂ QSTAB(G). It is, therefore, natural to us...
متن کاملUnderstanding Imperfection
Because of their inherent abstraction, systems ideas are not themselves sufficient for gaining scientific knowledge or solving practical problems, but they can be a source of insights into the universality of imperfection, insights which can contribute to a new scientific world view. Systems theory offers a metaphysics, or more precisely an ontology, of imperfection. Through it, we can heed Spi...
متن کاملGraph Imperfection
We are interested in colouring a graph G=(V, E) together with an integral weight or demand vector x=(xv : v # V) in such a way that xv colours are assigned to each node v, adjacent nodes are coloured with disjoint sets of colours, and we use as few colours as possible. Such problems arise in the design of cellular communication systems, when radio channels must be assigned to transmitters to sa...
متن کاملCourage for simplification and imperfection in the 21st century assessment of "Endocrine disruption".
"Endocrine disruption" is a public and political buzzword that has and is still receiving high media attention. Based on the latter, numerous tiered testing strategies have evolved that should ensure that humans will not run a health risk due to the voluntary or involuntary exposure to endocrine active compounds (EAS). An analysis of the currently available knowledge on EAS mediated endocrine d...
متن کاملCharcot's irony and sarcasm.
Jean-Martin Charcot is considered the father of modern neurology and was the first neurologist to hold a professorship of international stature devoted to the study of the diseases of the nervous system. His biographers paint an image of an austere presence, reserved manner, shyness, economy of gestures and an impenetrable, impassive face. However, a wry and sarcastic side of Charcot can be dem...
