Posts: 13 Country : Slovakia | muhorka posted @ 2015-03-05 8:40 PM I agree with you kiwijam. Now it seems, that it´s better to solve easier puzzles than harder one, because this puzzles should be more probably discarded. Your suggestion is fine, but it´s hard to predict number of solvers. And the other problem is, that players doesn´t solve some puzzles in real time. They only print them and solve "how they can". For example, if I do not like scrabble puzzles, then I only print it and solve for a day (not because, i´m not able o do it faster, but only because I know, that I will solve it longer than 1 hour). So my time is not around two hours (as I solve it), but around 24 hours. And if you want to use formulas, where same number of solver appear, my 2 hour time should change the amount of points, if I should solve in real time. So the trouble is with people, whose do not solve "in real time". What about faktors for every puzzle, to be used to multiplying the result? For example the hardest puzzle should have factor 2 and easiest puzzle should have factor 1. Or anything similar to that. But faktors should reduce the differences between puzzles at least for some players. |

You don't need to predict the number of solvers. For example, after last year we could use n=212 for all ten puzzles. Then the rank bonus is the same amount for each puzzle. |

Posts: 774 ![]() ![]() ![]() ![]() ![]() ![]() Country : India | rakesh_rai posted @ 2015-03-05 8:40 PM Based on the inputs in this thread, we found that the hardest puzzle indeed gets eliminated for a majority. In effect, it is true that the hardest puzzle has minimal say in the rankings, especially near the top of the standings. So we are coming up with a revised structure for points table as below. Do share your thoughts on this. This uses the easiest puzzle as a reference. We'll review post-marathon if this addresses the problem or not. (Changes are in red) 2015 Points StructureCompared to 2014,Similarity : 1) Fixed points (50) if the puzzle is solved. 2) Variable Bonus points if the puzzle is solved within 60 minutes. 3) The bonus point is normalized (so the bonus point has a maximum limit) 4) A player's bonus is dependent on his Rank and on his solving time. Difference : 1) The number of "bonus-getters" in the easiest puzzle will be used as the basis for all ten puzzles, for variable bonus. DETAILS ======= There are 3 score components if a puzzle is solved correctly. 1) Fixed: 50 points (the player will get this even if you start it on 6th and finish on 15th) 2) Rank Bonus: The top ranked player for the particular puzzle gets 25 points. Every other player who has solved the puzzle within 60 minutes, gets 25 * (N + 1 - player's rank) / N where N is total number of players who have solved the easiest puzzle within 60 minutes. 3) Solving Time Bonus: The best player for the particular puzzle gets 25 points. Lets say, Number of players who solved a puzzle in less than 60 minutes is C. Case 1: C <= N/2: (Harder puzzles) - A linear distribution between 25 and 25 * (1 - C/N) will be used between the fastest solver and the last player with bonus, based on solving time. - Highest bonus =25 - Lowest bonus = 25 * (1 - C/N) Case 2: C > N/2: (Easier puzzles) - A linear distribution between 25 and 12.5 between the fastest solver and the (N/2) th player, based on solving time. - And, a linear distribution between 12.5 and 25 * (1 - C/N) between the (N/2) th player and the last player with bonus, based on solving time. - Highest bonus =25 - Lowest bonus = 25 * (1 - C/N) |

Posts: 18 Country : India | Yajendra posted @ 2015-03-05 8:40 PM That means 100 is the maximum score a person gets (by the person who solves fastest correctly) : 50+25+25. Am I getting it right? |

You can use any of them for solving as per your convenience. I would advise the LMIans to prefer the one with the solid lines as my printer had a problem with the former and completely missed printing the dotted lines in between.I would stop myself short here by saying that the Fillomino puzzle by itself is absolutely delightful and perfect!!!Good luck to all! |

Posts: 8 Country : Greece | term posted @ 2015-03-06 7:24 PM Fillomino seems to suffer the slightest ambiguity at the very end, and not affecting the key (unless I somehow messed up): R13C2 and R13C3 contain some permutation of 20,1. |

Posts: 67 ![]() ![]() ![]() Country : France | Puzlifouk posted @ 2015-03-08 6:45 AM It's half-time for me (5 puzzles solved). This contest is always so interesting. A question about the results : because of the calculation, it is not possible to have the complete score, with bonus, before the competition ends, but we could see the problems solved, the time used... Is this "the results that will be available soon ?" |
