Police

Your interstellar police squad has tracked down some dangerous revels to a cluster of seven small planets. Now you must apprehend them quickly before their reinforcements arrive. Of course, the revels won't stay put. They will try to dodge you by moving from planet to planet. But, you have an advantage. Every hour, Your cruiser can warp between any two planets while their beat-up ship can only go to an adjacent planet every time. These revels don't like to stay put. Every time they can warp, they will. Your scouts tell you that the approaching revel fleet is ten hours away. You can't risk letting the revels get away. Can you devise a plan that will guarantee catching the revels in ten moves or less?
