Sting SF 20

[lech]

The next part of the project Sting is here:
http://www.mediafire.com/file/69p14t6gj ... 0.zip/file
There are some important changes and corrections.

[lech]

The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames.
Here are positions dedicated to all engines to test so-called by me "quasi-intelligent" theirs abilities.

Set parameters: "threads" to 1 and "hash" to 1024 and clear hash before each of items.
Don't use such external tricks like: rule-50 changing, null-move disabling, special parameters and others.
The external tools like: MultiPV, tablebases, "backward-forward" and "Monte Carlo" are not welcome too.

"WIN" means the correct solution and some non-zero plus score.

Don't do the test in a machine way. Test and analyze each of items separately!

Thank you, it is always a good day when a new version of Sting is released

[Jouni]

How many of these 100 positions Sting solves in reasonable time limit 1/5/10 minutes?

[Vinvin]

How many of these 100 positions Sting solves in reasonable time limit 1/5/10 minutes?

+ what are the improvements since version 19 on this set ?

[lech]

How many of these 100 positions Sting solves in reasonable time limit 1/5/10 minutes?

+ what are the improvements since version 19 on this set ?

The "iq" test contains examples of many groups of problems which need a special code. Without the code alpha-beta engines (probably NN too) are not
able or have a serious problem to solve these postions without dirty tricks. Each version of Sting is to solve the problems in a better way avoiding a selective code.

[Jouni]

Latest Crystal solves about 65/100 in one minute limit and 4 cores. With "solving" I mean first move or win/draw.

Many studies have too long solution for searching.
Example: Neghina's study (win)

If an engine returns 7. c6 (searching) move it is only one way to get the second part of the study: stop the searching and skip the moves and start searching from the next position or start auto-playing.
