Hello, While going through old Codejam problems, I find that the minimum distance is wrong with the example solution for Problem B (of round 1C of 2009), case 2 and 3:
( http://code.google.com/codejam/contest/dashboard?c=189252#s=p1 ) Case 2: The position of the center of mass at time t is: [-18, 3, 0] + t * [3, 0, 0] giving tmin = 6 as shown in the example output. Substituting tmin = 6 in the above expression I get: [0, 3, 0] which is 3 away from the origin, not 1 as in the example output. Case 3: For the center of mass I get: [5, 14, 4] + t * [4, -6, 2] where I get again tmin = 1 as shown in the example but substituting this I get: [9, 8, 6] which is 13.4536240471 away from the origin, not 3.36340601 as given in the example. Can anybody convince me of the contrary ? (or could this be updated on the contest analysis ?) I apologize if I state the obvious... best regards, Andre (In addition, just as a test, I downloaded the solution of one of the top contestants for this problem, ran the small input set and submitted it. The verifier does not accept the output ...) -- You received this message because you are subscribed to the Google Groups "google-codejam" group.
