For all previous competitions, you have to visit the respective pages. See this link for monthly tests and this link for mock tests.

This might have sounded a silly question as I look at it now, but this was all because I use a MSI laptop with tiny screen and thus the resolution is set in such a way that I sometimes do not see things in the edges of the screen unless I scroll it:-) Thanks again and sorry for molesting anyway. |

Country : India | Filling in Country field must before you can take this test. This is done primarily because of IPC next week.
When you visit EverGreens page, the login space will be slightly different from how it looked earlier.
If you already have country updated, you can login after filling in username and password.
But if your country is blank (i.e. you have never updated the country field earlier ), you have to fill in the country field before you can start the test. Otherwise, you will get error message.
To know if your country is blank OR filled, you can visit Settings. You can update the field there too.

Country : India | Based on the discussion during Broken Pieces, partial Bonus will be awarded in this test.
We'll use Ziti's formula in this test, as an experiment basis.
If all puzzles are not correct, a factor will be computed based on your score. Your time bonus will be (number of minutes saved * this factor * 8 ).
Factor = (Points earned - 4 * points missed ) / (Total points )
In this is case, Total Points will be considered as 575.
'Points earned' will be computed with any group bonus etc.
See table below, for how much the factor will be based on the points (without group bonus )

What if someone submit all puzzles ~10 mins before time limit with one error and later he realizes he made that error.
So he will submit answers again (this time correct) 1min before time limit.
With current partial bonus system it means that solver could lose points for that action.
What points that solver will be awarded? |

We'll just consider the final submission, and not intermediate submissions.
It is not necessary that the player will lose points because of that action. There are several parameters which will limit the partial bonus. |

I think anyone who scores more than 465 points gets the bonus irrespective of whether he submits all the puzzles or few wrong puzzles..........Am I correct???? |

Administrator
Country : India | Neeraj, you are correct.
Please check the factor table again.
If a players submits everything in 70 minutes, and gets a score of 465 he gets a bonus point 3.
If a players submits everything in 70 minutes, and gets a score of 500 he gets a bonus point 28.
If a players submits everything in 70 minutes, and gets a score of 575 he gets a bonus point 80.
It does not matter if some puzzles are wrong or not submitted. They are treated same way.

Administrator
Country : India | so, it is obvious that the player getting 465 in 70 minutes must try for few more puzzles in the remaining 10 minutes rather than getting satisfied with 3 bonus points. |

But that is what happens with internet tests, and it did not detract from the overall enjoyment. Good work, thank you Deb. I agree with you. After some 'guessable' answer keys in BP, I re-did some of the answer keys for this test, and in that process some answer keys became much longer than probably needed, and hence error-prone.
But yes, as you mentioned, it is very important to strike a balance in the answer keys - between being guessable and too-lengthy/error-prone. |

Country : Hungary | Zormac posted @ 2010-09-05 8:15 PM Good test, thanks guys.
Unfortunately, I wasn't very well prepared for it in technical terms - at the start, I printed the test, realising that the colour toner is very low, meaning that some of the puzzles came out in a very low quality, unsuitable for solving. I started to solve those that were visible enough and started a 2nd printing, this time in greyscale - this was when the black toner gave in too! :-(
Of course, that doesn't explain the three submission mistakes I made, in each cases the error was made at the time of determining the submission codes over a correctly solved puzzle (overlooked an X, a double bridge and a turn in Anglers, respectively). Which is part of the contest, I guess, so it's a skill to work on later!
Cheers

Can a line cover 2x2 square? can a puzzle have unique solution when a line covers 2x2 square?
A rule that a line can't cover a 2x2 square may be needed in some puzzles, to force a unique solution.
If such a rule does not included, one may use the fact that the puzzle has a unique solution, without this rule.

2. In half dominoes, does the half dominoes should be placed in the marked 3x3 boxes, without overlapping, as in the example?

In H20 the atoms cannot be connected as H-H-O. They can only be connected as H-O-H.
In half dominoes the dominoes need to be placed in the marked 3X3 boxes without overlapping.

A great selection of puzzles which I will now go away and finish at leisure! Need to get the brain cells ticking over a little quicker! |

Country : Israel | amnon posted @ 2010-09-06 5:04 AM First I add my thanks for the nice puzzles.
The interesting bonus system requires different approach for the selection of problems to solve.
There is some problem with my submission of the Queens park puzzle. I entered the right solution in the form (I can still see it) and I submitted 3 answers after this one which were received correctly. It tells me that answers to 13 puzzles were submitted, which is the number I sent, including the Queens park.
However, in the results page I see the Queens park, but with empty solution.

We have tried to draw inspiration from the Brazilian Puzzle Championships and the WPC in Brazil where they gave extra credit to for participants attempting puzzles across different puzzle types.

Country : United States | motris posted @ 2010-09-06 12:31 PM Thanks again for running a great puzzle test!
Re: the bonuses, both in my planning before the test and during the test, I figured I would be able to keep track of the "rows" and use that to know if I should stick with a puzzle or not, but it was more difficult to follow the columns or game-plan in the same way since it was less obvious on a single page of the answer sheet that some set was being completed. Perhaps a more involved user-interface would help, but my general opinion is that "group" bonuses can be a good idea but doing two different sorts as here was a little more complicated than its value.
One different aspect in Brazil is that the test-setters wanted people to spread out their work, so they used variable scores for the puzzles in each part, where here the bonuses seemed to encourage people to focus within a difficulty level or puzzle column. Perhaps the right bonus is some multiplicative factor like (# of group A solved * # of group B solved * # of group C solved ...)^some exponent. Then if you want a test with arithmetic puzzles and loop puzzles and sudoku and such grouped into sections, solvers have a motivation to go between the sections more. I'll think about this idea more for the future to see if a good system avails itself. |
|
debmohanty
Country : India | @motris,
I agree with both your points about this test
1) grouping should be done based on puzzle type, rather than difficulty
2) 2 different bonus system was not necessarily nice, since little planning about it can be done. May be if the puzzles were grouped by 'types' and same column had different point-puzzles, it would have made little more sense. [so that every player has to solve easy puzzles and difficult puzzles to get column bonus]. But that might just make it more complicated. |

@motris: I disagree that keeping track of the columns was hard, you just needed to have the table next to you and cross out all the puzzles you solved.
But there is another disadvantage with those multidimensional bonuses: One mistake might be punished 3 times (with time bonus 4 times). E.g. I lost more than 100 points by not counting the given 2 in the polymino puzzle. |

This was the icing on the cake of a horrible performance from me...
Excellent set of puzzles which has been rewarded by a great number of players from all over the world. The formula chosen with a relatively short time, good mix of puzzles from relatively easy to not too difficult, and two days time to play seems to be the winning combination. Hope to see more.
Will never thank enough puzzlers like you who spend time in organizing contests like this one.

Country : India | Thanks for some excellent puzzles. I was able to look at only A and E groups in the given time and the puzzles were indeed as expected - easy in group A and not-so-easy in Group E. Darts was also very easy - Later when I looked at it, I could solve it visually. ABCD 2nd end view was a good idea and I have not seen this elsewhere. I was not able to make much of a headway in Dutch Loop, except for the border rows/columns. Can someone explain good logical starting points for solving the puzzle.
Regarding the bonus point system, it was a nice multi-dimensional concept and must have kept the participants busy with a parallel calculation. I won't be able to comment whether it was good/effective or not. Looks like it probably was. But others who got bonus points, or narowly missed bonus points, can probably comment on it. So far, I have already seen three comments already where participants suffered to the tune of 100+ points because of one mistake. |

Country : United States | Thanks for the fun puzzles. Not sure that I saw the connection from a difficulty perspective or grouping perspective to attribute bonuses, but I will leave that to the higher dwellers to figure out. I am a bit of a turtle when it comes to puzzles, so a sprint test like this is not my forte, but the medium level and size of the puzzles did force my hand and I very much enjoyed the contest.
On a side note, this is probably the first time I can say that I beat Nick Baxter at anything. In turn, if Nick wants to turn over the responsibility for the US Team to me to run going forward, I accept.
Thanks again. Looking forward to the next tone already.
