- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 2 deterministic, 1 nondeterministic) and one nonterminating remainder module.One deterministic module has affine ranking function i and consists of 4 locations. One deterministic module has affine ranking function i and consists of 3 locations. One nondeterministic module has affine ranking function i and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 7 locations.

- NonterminatingLassoResult [Line: 10]: Nonterminating execution
Found a nonterminating execution for the following lasso shaped sequence of statements.
Stem:
[L6] int i;
[L7] i = 0
[L9] COND TRUE i < 100
[L10] COND TRUE i < 50
[L10] i = 51
[L9] COND TRUE i < 100
[L10] COND FALSE !(i < 50)
[L11] i = 49
[L9] COND TRUE i < 100
Loop:
[L10] COND TRUE i < 50
[L10] i = 51
[L9] COND TRUE i < 100
[L10] COND FALSE !(i < 50)
[L11] i = 49
[L9] COND TRUE i < 100
End of lasso representation.
