There is an algorithm for this ----------------------------------- ecookman Tue Feb 24, 2009 8:12 am RE:grade 2 computer test in China ----------------------------------- lol i fail.... ----------------------------------- andrew. Tue Feb 24, 2009 9:02 am Re: RE:grade 2 computer test in China ----------------------------------- lol i fail....Me too :cry: ----------------------------------- Tallguy Tue Feb 24, 2009 2:21 pm RE:grade 2 computer test in China ----------------------------------- :( i would so fail grade 2, lol but i finally got it YAY!! ----------------------------------- ecookman Tue Feb 24, 2009 3:20 pm RE:grade 2 computer test in China ----------------------------------- if only they could jump backwards and like tall guy...finally ----------------------------------- bugzpodder Tue Feb 24, 2009 3:51 pm RE:grade 2 computer test in China ----------------------------------- service unavailable FAIL ----------------------------------- saltpro15 Tue Feb 24, 2009 4:05 pm RE:grade 2 computer test in China ----------------------------------- @A.J., I would like to see an algorithm for this, could it be done along the lines of dynamic programming with a BFS? it seems quite difficult to me ----------------------------------- DanielG Tue Feb 24, 2009 4:13 pm RE:grade 2 computer test in China ----------------------------------- not really, look at the puzzle and you will notice that at any point only 1 move is accurate and the inaccurate can be noticed right away (after making the mistake), so even dfs should probably work. ----------------------------------- A.J Tue Feb 24, 2009 4:29 pm Re: grade 2 computer test in China ----------------------------------- @A.J., I would like to see an algorithm for this, could it be done along the lines of dynamic programming with a BFS? it seems quite difficult to me the algorithm doesn't have to do with DP, BFS, DFS, etc... look at 'empty space'...what do you notice to the movement of it? ----------------------------------- phleet Fri Feb 27, 2009 12:02 am RE:grade 2 computer test in China ----------------------------------- I question why this "Grade 2 Test from China" is in Portuguese.. ----------------------------------- matt271 Sun Apr 05, 2009 5:15 pm RE:grade 2 computer test in China ----------------------------------- wow that took me at least 2 min ----------------------------------- matt271 Sun Apr 05, 2009 5:15 pm Re: RE:grade 2 computer test in China ----------------------------------- I question why this "Grade 2 Test from China" is in Portuguese.. maybe they are learnning logic, Portuguese, and computer skills all at the same time :] ----------------------------------- A.J Sun Apr 05, 2009 6:41 pm Re: grade 2 computer test in China ----------------------------------- I question why this "Grade 2 Test from China" is in Portuguese.. maybe they are learnning logic, Portuguese, and computer skills all at the same time :] Or maybe this is just a Grade 2 test from Brazil (and they accidentally added the word 'China' in there for some reason). Possibilities... ----------------------------------- DanielG Sun Apr 05, 2009 6:42 pm RE:grade 2 computer test in China ----------------------------------- or maybe it's not a test at all; either way, it is still a nice puzzle. ----------------------------------- saltpro15 Sun Apr 05, 2009 7:08 pm RE:grade 2 computer test in China ----------------------------------- well considering how it's just basically clickity-click and requires no logic, I'd say this is a pretty lousy test. Maybe getting them to write a basic calculator or something would be a good test. ----------------------------------- DanielG Sun Apr 05, 2009 7:19 pm RE:grade 2 computer test in China ----------------------------------- it requires a bit of logic, if you just click randomly than you fail (unless you are really lucky) ----------------------------------- saltpro15 Sun Apr 05, 2009 7:37 pm Re: grade 2 computer test in China ----------------------------------- green brown brown green green green brown brown brown brown green green green brown brown green here's the answer, for those who are truly stumped
