Description

The invention relates to a chess computer according to the preamble of claim 1.

Chess computers have been increasing in recent years Sales figures on. Your skill level is through advancement of program and hardware steadily increased. In the higher difficulty levels it is Skill level so high today that even good ones Chess players (club players) a game against one Chess computer makes sense.

In the course of development, the devices are replaced by additional ones Facilities, such as displaying the number of moves, the playing time, Position evaluation, storage of the current Lot, etc., become more attractive to the user.

From US-PS 42 20 992 is a portable device for Analyze a golf game or another Sport known as tennis, bowling, etc. The device has input keys, by means of which in the course one or more golf rounds can be entered, whether one shot too far, too short, left or right deviated, etc. has failed. After completing the Game, the user can query how many or what percentage of blows z. B. failed too short are. The device contains a long-term supported storage.

The device is not designed to show game results such as "victory" or save "loss". There is also no automatic deletion of old game results.

The invention is based, for one Chess computer of the type mentioned at the beginning, device useful and interesting for the player specify.  

This object is achieved by the contained in claim 1 Invention solved.

The following is the function of an embodiment the invention explained in more detail.

For this purpose, the computer has a memory for each difficulty level, in which the results of the last a games, e.g. B. the last 10 games of this level are saved. The memory is designed or supported so that its contents are retained even when the supply voltage is switched off. One or more additional memories, or even a memory already present in the computer, can be used for this.

By reading in the result of the 11th game the result of the 1st game deleted, so that only the last 10 games are considered.

As a game result z. B., as usual, for one Loss = 0, for a draw or standoff = 1/2 and for one Victory = 1 can be read. Aborted games will be counted as a loss. Incomplete lots, such as B. Chess problems are not taken into account.

Here, z. B. result (level = 6):
Results: 1 1 0 0 1/2 1 1/2 1 1/2 1;
Result total: 6.5.

The total of results for each level of difficulty is then weighted with a factor that takes into account the level of difficulty or the computing depth of the computer. In the simplest case, this is the number of the game level. It then results, for. B .:
(Number of levels = 7)

A dash (-) means that no level 1 games were played. If in a stage less than 10 Games have been played, those not played Games rated 0.

Finally, the sum of the weighted result totals formed and as the user's skill level displayed, in this case 157. How to easily determine can have the maximum attainable skill level here when winning all games at all levels lead to a value of 280. Game losses or winnings in the desired way to a long-term reduction or increase the displayed skill level.

It is also expedient to switch off the device make so that when used by a second Player's skill level is not changed.

With a little more effort, the facility can also be installed multiple times for multiple users. It is each user is assigned a key figure that precedes a Lot must be entered.  

Finally, it is useful to have the total number save played games.

By the device according to the invention, it is for allow the player to determine how his Skill level changes over time. Next is one Comparison of his skill level with the skill level other owner of the same chess computer possible. When standardizing the procedure is also a Comparison between owners of different makes possible.
