|The idea of abstract interpretation is to consider program properties at each |
program point as elements of a lattice. ... 4.2 Polyhedra Abstract Domain One of
the most used instanciation of abstract interpretation is the interpretation over the
|3.6 Abstract Interpretation of Constrained Horn Clauses Abstract interpretation [|
10] is a static program analysis techniques which derives sound over-
approximations by computing abstract fixed points. Convex polyhedron analysis (
CPA)  is ...
|Finally, we present some methods that work well for accelerating the |
convergence of sequences of real values. 3.1 Polyhedra Abstract Domain A
convex polyhedron is a subset of Rn defined as the intersection of finitely many
|(which represents an edge) is a member of the cycle which defines a polygon (|
representing a face). We say that the polyhedron is a realization of the underlying
abstract polyhedron. If all faces of a geometric polyhedron are simple polygons, ...
|The regular polyhedron (3, 6)(i,i). It is clear that the Petrie operation tt is involutory|
, so that n~ ' = tt and ( QT )'T = Q. If 0* is isomorphic to Q, then we call Q self-Petrie
; it should , however, be observed that a self-Petrie polyhedron and its Petrial ...
|An abstract spherical polyhedron is formed by a 2-connected planar graph (V, E) |
drawn in the plane, without self-intersection (Figure 8 A). The vertices of the
polyhedron are the vertices of the graph. The edges of the polyhedron are the
|Regular mutual position of simplices of the polyhedron means that any two of the |
simplices of the polyhedron either are ... there is a one–one correspondence
between actual realizations of polyhedra by simplices and abstract complexes.
|Our aim is to construct the convex hull of the set V while remaining in the frame of |
abstract cell complexes without using notions from the Euclidean geometry. We
consider the convex hull as an abstract polyhedron according to the following ...
|Weakly relational domains such as octagons , intervals , octahedra  and |
the TCM domain , avoid these conversions by considering polyhedra whose
constraints are fixed a priori. The abstract domain of Simon et al.  considers ...
|This, in turn, suggests the problem, important for the abstractionists, of concrete |
realizations of an abstract geometrical structure that we shall illustrate on a
simple example of an abstract convex polyhedron. Such an abstract convex ...
