League optimizers 2017th

Wow, Zafer! That's an awesome improvement.

Hi Svetlana. Thanks. Actually your solution was incredible. I just tried to add some more points and luckily could perform such an improvement. Maybe there exists another solution with 5000 or more pts

OBJECTIVE: Put pentominoes (12-24) and one closed loop into given grid. Use letters F, I, L, N, P, T, U, V, W, X, Y, Z to mark pentominoes, and letter A to mark loop. Every pentomino must be used at least once and at most twice. Overlaping (pentominoes and loop) is not allowed. Pentomino can be mirrored and rotated. Different pentominos can touch by side, but same pentominoes can touch only diagonally. Loop can touch itself only diagonally.
CALCULATION: Row/column score is displayed right and bellow the grid as P*L*E (Number of Pentomino segmensts, Loop segments and Empty cells in that row/column). Final score is sum of loop length and scores for every row/column. For every pentomino which is used twice you get bonus of 50 points. Maximize final result.

ZADATAK: U mrežu treba ucrtati proizvoljan broj pentomina (12-24) i jednu zatvorenu petlju. Pentomina označite uobičajenim slovima (F, I, L, N, P, T,U, V, W, X, Y, Z), a petlju označite slovom A. Svaki pentomino morate upotrebiti najmanje jednom, a najviše 2 puta. Pentomina se mogu rotirati i reflektovati. Različite figure se smeju dodirivati stranicom, a iste samo dijagonalno. Preklapanje nije dozvoljeno. Petlja može samu sebe dodirivati samo dijagonalno i ne sme prelaziti preko pentomina.
OBRAČUN: Desno i ispod mreže prikazan je obračun svakog reda i svake kolone, koji predstavlja proizvod P*L*E (P je broj delova pentomina u redu ili koloni; L je broj delova petlje u redu ili koloni; E je broj praznih polja u redu ili koloni). Sabiraju se svi redovi, sve kolone i dužina petlje, a za svaki ponovljeni pentomino dobija se još 50 poena. Maksimizujte svoj rezultat.
