What remains to be done here is to try to find a solution using the minimum number of moves, instead of just using any old solution. Or maybe add the Lights Out 1 and Lights Out 7 or 8 (for a progression in difficulty) in the Classic Games Puzzles. Solutions to any board position can be found in O(n^2) time using the row-reduction information. 3 If the light at B5 is on then toggle B1 and E1. 2 If the light at A5 is on then toggle D1 and E1. 1 Chase the lights down to make all lit lights in row 5. If all the buttons except for the bottom row D and/or E are lit, you've got an insoluble one. If the leftmost lit button is B, press the top row A and bring them down. Each click toggles the selected cell as well. If the leftmost lit button on the bottom row is A, press button B on the top row and 'bring down' the lights. Lights Out is a commercially marketed product whose analysis admits a linear algebra framework analogous. Turn all the lights out using as few clicks as possible.

To choose a random solvable board uniformly from the space, a random 0,1-vector is chosen and multiplied onto B, which takes O(n^2) time. Lights Out Classic Variations of the Lights Out Puzzle Introduction Solving the Lights Out Classic The Algorithm Algorithm 1.2 Number the rows 1-5, the columns A-E. Lights Out is an exciting, entertaining, addictive, and completely free brain puzzle game. Using the row-reduction information for M, a basis B is extracted for this subspace in O(n^2) time. Lights out is a crossword puzzle clue that we have spotted 4 times. The column space of M is the subspace corresponding to all solvable boards. Gauss-Jordan Elimination is then performed to put M into reduced row-echelon form: this takes O(n^3) time, and is only done when the size or shape of the board, or thepattern of neighbours changes. These vectors are then assembled into an n \times n matrix M, called the move matrix. By querying each cell about what it toggles on and off, form a vector corresponding to each possible move.
Take some board configuration with n cells. Lights Out is a family of hand-held electronic puzzles by Tiger Toys featuring a contiguous arrangement of red lighted buttons. Generating and solving boards efficiently
