2 Omega Project Source Release, version 1.1
4 This is verions 1.1 of the Omega Project software, including:
5 * The Omega library, a set of routines for manipulating linear constraints
6 over integer variables, Presburger formulas, and Integer tuple
8 * The code generation library, a set of routines for generating code to
9 scan the points in the union of a number of convex sets.
10 * The Omega calculator, a text-based interface to the Omega library
11 * Petit, a educational/research tool for analyzing array data dependences
12 * The Uniform library, a source to source parallelizing transformation
13 system, described in Wayne Kelly's Ph.D. dissertation.
15 Some new or recent features:
17 * An exact convex hull computation
18 * An improved system for handling inexact relations, including taking
19 upper and lower bounds, checking for subsets, and checking tautologies
20 * Better handling of existentially quantified variables: we can now
21 negate and generate code for sets like:
22 {[i] : 1 <= i <= n && exists (alpha : i <= 10 alpha <= i+k)};
23 * An Example operator, that gives a sample solution to set or relation.
26 Users with code that uses previous versions of the Omega library may
27 need to make some changes to their code in order to comply with the new
28 functions for checking subsets, satisfiability, and tautologies.
