Date "solving" was first used in popular English literature: sometime before 1415. (references) |
(From Wikipedia, the free Encyclopedia)
A two-player game can be "solved" on several levels.
- Ultra-weak: In the weakest sense, solving a game means proving whether the first player will win, lose, or draw from the initial position, given perfect play on both sides.
- Weak: More typically, solving a game means providing an algorithm which secures a win for one player, or a draw for either, against any possible moves by the opponent, from the initial position only.
- Strong: The strongest sense of solution requires an algorithm which can produce perfect play from any position, i.e. even if mistakes have already been made on one or both sides. For a game with a finite number of positions, this is always possible with a powerful enough computer, by checking all the positions. However, there is the question of finding an efficient algorithm, or an algorithm that works on computers currently available.
Solved games
- Awari (a game of the Mancala family)
- Solved by Henri Bal and John Romein at the Free University in Amsterdam, Netherlands (2002). Either player can force the game into a draw.
- Connect Four
- Solved by both Victor Allis (1988) and James Allen (1989) independently. First player can force a win.
- Gomoku
- Solved by Victor Allis (1993) First player can force a win.
- Hex
- Completely solved (definition #3) by several computers for board sizes up to 6x6.
- Jing Yang has demonstrated a winning strategy (definition #2) for board sizes 7x7, 8x8 and 9x9. [1]
- John Nash showed that all board sizes are won for the first player (definition #1).
- The discovery of an efficient general algorithm for an NxN board is unlikely as the problem has been shown to be NP-hard.
- Nim
- Completely solved for all starting configurations.
- Nine men's morris
- Solved by Ralph Gasser (1993). Either player can force the game into a draw. [1]
- Pentominoes
- Weakly solved (definition #2) by H. K. Orman. It is a win for the first player.
- Qubic
- Solved by Patashnik (1980).
- Three Men's Morris
- Trivially solvable. Either player can force the game into a draw
- Tic-tac-toe
- Trivially solvable. Either player can force the game into a draw
Partially solved games
See Also: Board game complexity
- Checkers
- Endgames up to 8 pieces have been solved. Not all early-game positions have been solved, but almost all midgame positions are solved. Contrary to popular belief, Checkers is not completely solved.
- Chess
- Completely solved (definition #3) by retrospective computer analysis for all 2- to 5-piece endgames, counting the two kings as pieces. Also solved for pawnless 3-3 and most 4-2 endgames.
- Go
- Solved (definition #3) for board sizes up to 4x4. The 5x5 board is partially solved. [1] Humans usually play on a 19x19 board (which has an enormous complexity). Therefore solving the game appears very unlikely. On the other hand, a heuristic algorithmic solution might be achievable in the future. While not mathematically complete, it could give good results in practice, perhaps beating even the best human players.
- Reversi
- solved on a 4x4 and 6x6 board as a second player win.
- mnk-games
- It is trivial to show that the second player can never win. Almost all cases have been solved weakly for k <= 4. Some results are known for k = 5. The games are drawn for k >= 8.

In the past year, NIA-supported investigators also have looked at ways to improve standardized tests of memory, language, and other neuropsychological components in hopes of being able to better predict future development of AD. In one study, scientists at Harvard and the Massachusetts General Hospital examined whether it was possible to identify aspects of the Clinical Dementia Rating (CDR) scale to predict which people with “questionable” AD have a high likelihood of converting to a diagnosis of AD over time (Daly et al., 2000). The CDR is a semi-structured clinical interview that stages AD from 0 (normal) to 0.5 (questionable), 1.0 (mild), 2.0 (moderate), and 3.0 (severe), based on an assessment of six categories of function (memory, orientation, judgment and problem solving, community affairs, home and hobbies, and personal care).
