The HIARCS 13 UCI series requires a PC running MS
Windows 98, ME, NT4, 2000, XP, Vista or Windows 7 (all versions) with a UCI compatible GUI (a
Graphical User Interface is not included in the
package).
Shortly after your payment to purchase HIARCS is received you will be sent
an email with your personal license key to activate HIARCS and the download
details including a link to the download. Simply click on this link and save
your download (please note where you save the downloaded installer). Please
make sure you only use the installer on your computers and only those you
intend to use HIARCS 13 UCI. The reason for this is that the license key is
for your personal use only and displayed within the product. Once downloaded
and ready to install please locate and run the installer, e.g.
SetUpHIARCS13.1UCI
Double click the installer to run it. Once the installer is running please follow the straight forward
instructions to install the chess engine.
Please note the folder that the installer installs HIARCS 13 UCI in.
Once the installer has finished you will find the HIARCS 13 UCI engines, book, license and readme files
etc. will then be automatically installed on your machine in the folder you
selected.
Once the engine is installed you will need to create/add the HIARCS 13 UCI engine into your
favourite Chess GUI so you can use it. Please see the other question/answers below on this
page for how to do this.

After you purchase of HIARCS 13 UCI we will generate a personalised license name and key which will be emailed
to you.
First download the product and install it on your computer.
Now there is two main ways to activate the engine:
1) Activation before adding into a chess GUI - This is probably the
simplest way to activate the HIARCS engine. Open the folder in which HIARCS
13 is installed. To do this open a file browser and navigate to the folder
containing the HIARCS 13 UCI chess engine you want.
The default installation location for HIARCS 13 UCI is
C:\Program Files\HIARCS Chess\HIARCS 13 SP UCI
The default installation location for HIARCS 13 MP UCI is
C:\Program Files\HIARCS Chess\HIARCS 13 MP UCI
Please note on Winx64 "Program Files (x86)" will be used instead of "Program
Files".
Once you reach the installed Hiarcs 13 folder you will see the following:
Double click on the ACTIVATE-H13MP (or ACTIVATE-H13SP) batch file to pre-activate the HIARCS
engine by entering you license information in the following dialog.
alternatively you can activate using this method...
2) Activation when adding into chess GUI - Add/create the HIARCS UCI
engine in your chosen Chess GUI. When you load the engine in your chosen GUI
for the first time you will be presented with a dialog in which to enter your
license name and key.
Please note some chess GUIs have a very short time out when Adding chess
engines and this can make entering the key difficult. In that case either
select to Activate Later and enter the license key when loading the engine in
the GUI after it is created or use option 1 above.
Once your key is correctly entered (or copy/pasted) HIARCS 13 UCI will be
activated.
HIARCS 13 UCI is a major new release in the HIARCS series. It contains the
following major new features:
HIARCS 13 UCI contains the new protection mechanism which is highly
flexible for the customer and makes activation very straightforward.
With Arena 1.1 running select the Engines menu and select the "New Engine"
menu item as below:
You will then see a UCI/Windboard dialog box, select UCI and click OK
Now in the file browser navigate to the folder containing the HIARCS UCI
engine you want.
The default installation location for HIARCS 13.1 UCI is C:\Program
Files\HIARCS Chess\HIARCS 13.1 UCI
Please note on Winx64 "Program Files (x86)" will be used instead of "Program
Files".
Select the HIARCS 13.1 SP UCI (or HIARCS 13.1 MP UCI) engine to add it.
The engine will now be available in the Engine Management screen. You can
now start the HIARCS 13.1 UCI engine from the Engines menu
as follows:
Once the engine is first started if you have not pre-activated it you will
be asked to enter your name and license key to complete the activation of the engine.

Yes, HIARCS 13 is licensed for use on up to three of your personal computers simultaneously
provided they are your computers and HIARCS is only used for your personal
use.
Each HIARCS 13 UCI has its own personally identifiable license name and
key. Please keep this key private as you will need it to run free updates when
available.
No!
Both the SP and MP versions now have a flexible license key which is
not affected when you change your hardware or computer. So you can have peace
of mind that you can always use your HIARCS 13 purchase.
I certainly hope to provide some free updates. If progress is made with the
HIARCS 13 UCI series it is my intention to release updates to HIARCS 13 UCI
customers. For example if the 64 bit version of HIARCS 13 shows a significant
increase in chess strength I will release this version to HIARCS 13
customers.
However for obvious reasons I would not release a new HIARCS 14 engine for
free.
The default settings are believed to be the strongest although it is very
true to say we did not have time to test all the settings to be absolutely
sure. The changes from default settings which are most likely to have the
potential to be stronger than HIARCS 13 UCI default are
- Higher selectivity settings than 4 may offer improved performance.
Currently results on this are inconclusive.
- Some testers think Optimistic Search is better OFF at longer time
controls but we have insufficient data to be sure either way.
- The other setting worth experimentation is the Combinations OFF setting
as extra work has been done in HIARCS 13 on this.
- Against most programs that are weaker using the Hiarcs Draw value
(anti-contempt factor) can give even better results. The value of this
Hiarcs Draw value tells HIARCS to either prefer draws (positive values) or
avoid them (negative values). Against weaker programs a Hiarcs Draw Value of
-15 can be quite effective.
Please let us know your results and if you have found a better default for
HIARCS even if it is only against certain rivals.
You can find a full list of the settings and options on our
HIARCS UCI options page here.
This is a very difficult question to answer accurately because the strength
improvement varies depending on the opponent HIARCS faces and the time control
being used. It also requires literally thousands of games against various
opponents under strictly controlled conditions to determine the Elo
improvement.
Time will tell what the true strength increase is, we are very confident that
HIARCS 13 is significantly stronger than HIARCS 12.
Update HIARCS 13.2 is more than 100 Elo stronger than HIARCS 12.
The multiprocessor version of HIARCS 13 UCI when running on multi-core/processors
(of course!) gains a good speed up factor. The engine seems to scale quite
well and on two processors is about a factor of x1.8 times faster and on four
processors it is about 3 times faster than its single
processor little brother. On 8 core machines we have seen a speed up of about
a factor of 6.
In terms of Elo strength improvement I would imagine that on a dual
core/processor system it would be roughly about 50 Elo stronger and on a 4
processor system 90 Elo stronger. While a 8 core system would increase the
strength by about 130 Elo.
If you do any comparisons please let us know the results!
The current maximum number of CPUs supported is 16 but we hope to raise this
in the future once higher CPU support has been verified.
Yes, absolutely. The HIARCS 13 MP version can run on a single processor
system as well as the single processor version of HIARCS 13 UCI. With HIARCS
13 MP you have the flexibility that if you upgrade your computer to a
multiprocessor version in the future you are safe in the knowledge HIARCS 13
MP will utilise your new computer's CPU hardware to the full.
Purchasers of HIARCS 13 MP also receive a license for HIARCS 13 SP.
Even if you have a multiprocessor or multicore (e.g. Dual Core) system you
can instruct HIARCS 13 MP to use one or more processors up to a max of 16 CPUs.
HIARCS UCI offers set Elo strength play with customised
opponents from beginner at 750 Elo to Super Grandmaster at 3000+ Elo.
Depending on the GUI the way this Limited Strength option is employed varies.
The OwnBook engine parameter is on by default. This means HIARCS UCI will
access its own book and even learn good and bad openings if the book learning
option is on. However, you MUST turn the GUI book off or load an empty book so
that Hiarcs will be able to play from its own book. Otherwise the GUI will
play the book moves from another GUI book and not ask the Hiarcs engine for a
move in the opening.
Unfortunately the engine book cannot be displayed in a GUI because the UCI
protocol does not allow for it.
To provide the HIARCS opening book so each GUI can read and display it, it
would require that we produce the book in numerous different and contrasting
formats which would be very time consuming.
A Chessbase CTG opening book will be produced for purchasers of the
HIARCS Chess Opening Book Subscription product.
