9. What are Flash Memory and RAM used for in these devices?
Flash Memory is non-volatile storage, used to permanently store the board’s operating system (firmware), AI algorithms, pre-programmed puzzles, and master games. RAM (Random Access Memory) is volatile, high-speed memory used by the processor for active calculations, storing the current game state, and building the AI’s move-search tree during a game.
10. How do the ‘difficulty levels’ technically vary within an electronic chess board?
Difficulty levels are typically adjusted by modifying the AI’s search depth, computational time per move, and the complexity of its evaluation function. At lower levels, the AI performs shallower searches and might simplify its strategic considerations. At higher levels, it conducts deeper searches, considers more variations, and applies more nuanced positional evaluations, requiring greater processing power and time.
