EMPTY_SPACE_FIELD - Static variable in class Search
EMPTY_SPACE_PENTOMINO - Static variable in class Search
eraseDuplicates(int[][][]) - Static method in class PentominoBuilder: Erase duplicates in a array of matrices The input matrix stays unchanged
eraseEmptySpace(int[][]) - Static method in class PentominoBuilder: Erase rows and columns that contain only zeros

horizontalFlip(int[][]) - Static method in class PentominoBuilder: Flip the matrix horizontally It makes a copy, the input matrix stays unchanged
horizontalGridSize - Static variable in class Search

input - Static variable in class Search
introducesHoles(int[][], int[][], int, int) - Static method in class Search
introducesNotRefillableSpaces(int[][], int[][], int, int) - Static method in class Search: Check if the piece introduces larger, but not refillable spaces (which invalidates the solution) - assumes that the piece is already placed on the board!
isEnclosed(int[][], int, int) - Static method in class Search: Check if the location x, y is enclosed by other pieces (i.e.
isEqual(int[][], int[][]) - Static method in class PentominoBuilder: Check if two matrices are equal Assume they have the same size
isEqualRecursion(int[][], int[][], int, int) - Static method in class PentominoBuilder
isValidEmpty(int[][], int, int) - Static method in class Search: Helper function to check if a position is valid and empty (not out of bounds and not occupied by another piece)
isValidPosition(int, int) - Static method in class Search: Helper function to check if a position is valid (not out of bounds)

main(String[]) - Static method in class BackTrackTest
main(String[]) - Static method in class BruteForceTest
main(String[]) - Static method in class PentominoBuilder
main(String[]) - Static method in class PentominoDatabase: Main function used for visualizing and debugging reading the csv file with pieces Should not be called while searching for a solution
main(String[]) - Static method in class Search: Helper function which starts by default and gets the selected algorithm solver that the user wants to execute.
makeBigger(int[][], int) - Static method in class PentominoBuilder: Expands a smaller than size*size matrix to a size*size matrix It makes a copy, the input matrix stays unchanged Assume that the input is smaller than size!!
makeDatabase() - Static method in class PentominoBuilder: Make the database, created based on the pentomino's pieces defined in basicDatabase
moveToAbove(int[][]) - Static method in class PentominoBuilder: Move matrix to the left above corner Does not make a copy!

paintComponent(Graphics) - Method in class UI: This function is called BY THE SYSTEM if required for a new frame, uses the state stored by the UI class.
PentominoBuilder - Class in Unnamed Package: This class contains all the methods that you may need to start developing your project together with the representation of the pentomino's pieces
PentominoBuilder() - Constructor for class PentominoBuilder
PentominoDatabase - Class in Unnamed Package: This class takes care of reading all pentominoes and their permutations from a CSV Information abpout the structure of the CSV file (also included in pentomino.csv.README) Each line in the CSV file defines one permutation of a pentomino.

removePiece(int[][], int[][], int, int) - Static method in class Search: Removes a pentomino from the position on the field (overriding current board at that position)
rotate(int[][], int) - Static method in class PentominoBuilder: Rotate the matrix x times over 90 degrees Assume that the matrix is a square! It does not make a copy, so the return matrix does not have to be used
