....not as easily found as described in the paper. A system of inequalities is obtained by substituting U Gamma1 (K 1 ; K 2 ) T for (L 1 ; L 2 ) T . The actual loop bounds are found by applying Fourier Hotzkin elimination [14] to this system, for implementation details, look at [13]. Also note, that the transformation is valid if and only if for each distance vector (D 1 ,D 2 ) 0 in (L 1 ,L 2 ) we have U (D 1 ; D 2 ) T 0. There are some special cases of loop transformations : ffl Outer loop reversal, when the transformation is derived from the special reversal matrix ....
