Some notes about April Contest 2020

Please note this contest will have a slightly different format than regular LMI tests.

Key differences from regular LMI tests:
• There is no IB (i.e. no Instructions Booklet). If you have any questions about any puzzle, please ask here.
• The PB (Puzzle Booklet) does not have any password.
• You can download the pdf and start solving. Login at the contest page to start submitting.
• There is no time limit. You can submit until the contest ends.
• There will be some optimizer puzzles. Other puzzles will be very hard (compared to regular LMI tests)
• Same scores will have same rank (i.e. early submissions do not count towards rank)

The example does not comply with "A barrier must be placed between two vertically or horizontally adjacent cells if they contain consecutive digits." in at least 4 pairs. Is it correct that it is not necessary to have a bar bewetwewn every such pair.

My guess is that they aren't placed because they are irrelevant to the solve, i.e. not in the same row or column as any clue.

For puzzle 10, what's a street? Any stretch of white cells of length at least 2? Or do they have to go from one end to the other end of the grid?

in puzzle 3 hangers there is a sentence " if there are less than two circles in a row or column, there shall be no clue in that row/column".
Is the opposite also true? I mean, if in a row/column there are no clues, in that row/column there are less than 2 circles?Or could it be that clues for a row/column are omitted?

All rows and columns are fully clued, i.e. if a row or column does not have any clues, then there are less than 2 circles in that row/column.

Are the given loop fragments in puzzle 9 of length 1, or could they be part of segments of length 2?

Puzzle 8 : the 1-2-3-4-5 bottom clue line doesn't go til the upper left end (it stops 2 cells before). Is this normal or a display error ?

In puzzle 2, a table displays some letters and their values. Is this an illustration or a real mapping? As I see it, it does appear to be illustrative as many of the slots don't have words that satisfy 1 = A ,P, R. I have no way to know unless I understand the rules well. There is no example either

Streets of 1x1 are allowed?
Is this a town puzzle with 2x2 white areas not permissible? Or the white strips must be 1XN when evaliating the score? There is no clear demarcation in the description between puzzle rules and score evaluation.

In puzzle 2, the mapping of 1 - A,P,R given doesn't seem to fit the grid. Is it applicable to the grid or given as an example?

I think the given letters are part of the puzzle, not just an example. Remember that not every name is going to be used.

Not every name is used, but every slot needs to be filled in. There seem to be no names from the list matching the slots.

Puzzle 9 : what does "passing through all rows and columns" mean for the loop ? In the example, the loop doesn't use the top line of the grid at all...
