http://www.mediafire.com/?gqusn14dqu8ea5eA small improvement to Leopard. Now there are two game modes: a
positional and strategic, aggressive and a set of default, selectable by
the button (in the options UCI).
There are also 2 compilations "special": one for old computers with
little memory and limited resources (see folder "Old_CPUs" and a last
generation machine, with support for SSE 4.1, 4.2 and 4.3 but especially
with support functions POPCNT . These really put the "turbo" to the
program that can benefit from a significant increase in performance (see
folder High_End_CPUs).

--------------------
Leopard vers. 0.7b
--------------------
Changes:
-------------
0.7: initial release
0.7a: fix several bugs
0.7b: Net yield improvement in the game, fix more bugs, improvement of the game in the final. Now the program "makes it" good!
0.7c:
additional fixes "bugs", code cleanup, new feature to set mode
"Positional" compilation for new experimental version of "Turbo",
Compiling CPUs for "High End", support for up to 12 CPUs!
Style of play:
----------------
Leopard
has a very aggressive and fast-paced game, but for the players more
"quiet" mode you can set the "Positional" (using the button to be
selected in the settings of your UCI GUI), where the program will adopt a
much more solid and positional.
Recommended settings:
--------------------------
- Hash: from 32 to 2048 Mbytes. For the blitz is advisable to have it at 64 or 128
- HashPawns and HashPV: 16 to up to 64 Mbytes. For older machines with little RAM can be reduced to 2 or 4.
- HashEval: always double the Hash.
- SMP is set by default. For single processor machines it is best to disable it.
-
TC-Buffer is a kind of "deposit" where the program accumulates the
"reserve time" for not staying in time-trouble BLITZ IN GAMES. Each machine has its value: 200 on my laptop is great, but on other computers I have seen values of 500 and 1000. To experience. If you see that the program is always short of time, aumentatene the value of 100 units at a time.
- MultiPV: leave the default settings (1)
- Ponder: That is the computer "thinks" even when it touches the opponent. By default is disabled.
- LargePage: Enables a special mode where the program quickly moves large amounts of memory. Its activation significantly increases the speed and program performance.
Different versions:
------------------
They are distributed in 64-bit versions for Windows, Windows 32-bit and Linux 64-bit. For
each version there is a "basic" version that works on most machines and
a "HE" (High End) for high-performance processors (support POPCNT, MSSE
4.1, 4.2 and 4.3, etc..) Such as " Intel Core i7 ". It 'also includes an experimental version of "T" (Turbo) again for normal and high-performance machines.
List versions:
-----------------
- Win64: Version for Windows 64bit
- Win64HE: Version for Windows 64bit CPU "High End" (support POPCNT, MSSE 4.1, 4.2 and 4.3, etc..)
- Win64T: new experimental version of "Turbo"
- Win64THE: Turbo machinery "High End" (support POPCNT, MSSE 4.1, 4.2 and 4.3, etc..)
- Same way for 32-bit Windows systems (win64, win64HE, and win64T win64THE)
- X64: 64bit version for Linux systems
- X64HE: 64bit version for Linux systems with high performance (supports POPCNT, MSSE 4.1, 4.2 and 4.3, etc..)
- X64T: 64bit version for Linux systems, new experimental version of "Turbo"
-X64THE: Turbo machinery "High End" (support POPCNT, MSSE 4.1, 4.2 and 4.3, etc..)
~~~
These are "Beta" engines and most probably based on IvanHoe / Ippolit codes
Its slower than Houdini , its NOT using RobboBases , NOT any Bases and its doing as well if not better than any other engine without bases bases has done vrs Houdini
