The fantastic game *The Talos Principle* has these two dimensional Tetris like puzzles that I find annoying to solve. This program can solve them for me. First, specify the field size and puzzle pieces: ```rust fn main() { let field = Field::new(5, 5); let pieces = vec![ // Piece::cleveland_z(), // -_ // Piece::rhode_island_z(), // _- // Piece::teewee(), // Piece::hero(), // Piece::orange_ricky(), // ___| // Piece::blue_ricky(), // |___ // Piece::smashboy(), ]; let result = solve(field, pieces); match result { Some(field) => println!("{}", field), None => println!("No solution",) }; } ``` Then, get the solution with `cargo run --release`.
