Eighth Serbian Open Championship in Solving Optimizing Puzzles

[zhergan]

Hi,

Thanks for nice set of puzzles The grid sizes are big enough so we can see too many different solutions for each individual task Unfortunately I'm very busy in these days. But I hope I may try some arrangements for each task in the weekend. By the way I want to ask 2 questions about the puzzles:

1) In puzzle 3 can same pentominoes touch by side? In the example the 3 U pentominoes, the 2 V pentominoes and the 2 T pentominoes didn't touch by side. But this may also happened incidentally.

2)Is it enough to send the answers of 3 puzzles? Or must we also calculate the points we will get from puzzle 4 (The Link) and  send this result by explaining its components (I mean 3 points obtained by checking Puzzle1&Puzzle2, Puzzle2&Puzzle3 and Puzzle1&Puzzle3)?

And one last question: Does miscalculating the score obtained from a single puzzle makes our solution incorrect. Since the grids are big enough any puzzler can make such a mistake and we know that incorrect solutions will get 0 points. Then each of us must be very careful.

Thanks again for all contributors

Kind regards,

Zafer
