termination of the given Bare JBC problem could be disproven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 96 ms]
(2) JBC problem
(3) JBCToGraph [EQUIVALENT, 306 ms]
(4) JBCTerminationGraph
(5) JBCNonTerm [COMPLETE, 302 ms]
(6) NO


----------------------------------------

(0)
Obligation:
need to prove termination of the following program:
package simple.twoFloatInterv;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		TwoFloatInterv.loop(args.length);
	}

}


package simple.twoFloatInterv;

public class TwoFloatInterv {

	/*

	 */
	public static void loop(int i) {
		while (i > 0 & i < 50) {
			if (i < 20) {
				i--;
			}
			if (i > 10) {
				i++;
			}
			if (30 <= i && i <= 40) {
				i--;
			}
			
		}
	}
}



----------------------------------------

(1) BareJBCToJBCProof (EQUIVALENT)
initialized classpath
----------------------------------------

(2)
Obligation:

(3) JBCToGraph (EQUIVALENT)
Constructed TerminationGraph.
----------------------------------------

(4)
Obligation:
Termination Graph based on JBC Program:
simple.twoFloatInterv.Main.main([Ljava/lang/String;)V: Graph of 75 nodes with 1 SCC.
