Termination proof of /tmp/tmptYdFkx/Velroyen08-even.jar

Termination of the given JBC could be disproven:

0 JBC

↳1 JBCNonTerm (⇔, 442 ms)

↳2 NO

(0) Obligation:

JBC Problem based on JBC Program:

package simple.even;

public class Even {
	
	// does not terminate for negative numbers
	
	public static boolean even(int i) {
		while (i != 1 && i != 0) {
			i = i-2;
		}
		return (i == 0);
	}
}


package simple.even;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
	    int even = args[1].length();
	    if (args[0].length() % 2 == 0) {
	        even = -even;
	    }
		Even.even(even);

	}

}

(1) JBCNonTerm (EQUIVALENT transformation)

In the loop head node, references [i75] were interesting.
By SMT, we could prove
((initial_i75 <= 0 and initial_i76 <= 0 and 2 <= initial_i7) and (((path1_i75 = path1_i87 and path1_i177 = (path1_i87 - 2) and path1_i177 = res_i75 and path1_i76 = res_i76 and path1_i7 = res_i7 and path1_i75 = initial_i75 and path1_i76 = initial_i76 and path1_i7 = initial_i7) and (path1_i75 < 1 and path1_i87 < 0)) and ((res_i75 = res_i87 and res_i177 = (res_i87 - 2)) and !(res_i75 < 1 and res_i87 < 0))))
to be UNSAT. Consequently, the loop will not terminate.
