"isl is a library for manipulating sets and relations of integer points

bounded by linear constraints. Supported operations on sets include
|

intersection, union, set difference, emptiness check, convex hull, (integer)
|
|
affine hull, integer projection, computing the lexicographic minimum using
|
|
parametric integer programming, coalescing and parametric vertex
|
|
enumeration. It also includes an ILP solver based on generalized basis
|
|
reduction, transitive closures on maps (which may encode infinite graphs),
|
|
dependence analysis and bounds on piecewise step-polynomials.")

(synopsis "Library to generate code for scanning Z-polyhedra")
|
|
(description
|
|
"CLooG is a free software library to generate code for scanning
|
|
Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
|
|
reaches each integral point of one or more parameterized polyhedra.
|
|
CLooG has been originally written to solve the code generation problem
|
|
for optimizing compilers based on the polytope model. Nevertheless it
|
|
is used now in various area e.g., to build control automata for
|
|
high-level synthesis or to find the best polynomial approximation of a
|
|
function. CLooG may help in any situation where scanning polyhedra
|
|
matters. While the user has full control on generated code quality,
|
|
CLooG is designed to avoid control overhead and to produce a very
|
|
effective code.")
