Go up one level in this thread


There seems to be a problem at longer time controlls ... I just made a few
tweaks.  Lets see how this goes. I will give you an idea of the things I am
tweak .. this is my base config.  But what you will get is an idea of the things
that i am adjusting.

[King Safety = 150]
[Mobility = 100]
[Pawn Structure = 100]
[Passed Pawns = 100]

[Book Learner = aggressive]     * off|passive|moderate|strong|aggressive
[Position Learner = on]         * off|on
[Extended Book Learner = off]   * off|read|write|read&write

[Pruning = MISC_15]             * Time control
[Time Control = 85]            * With this parameter you can tune Rebel's time
control.
                                *< 100 : Rebel will play faster
                                *> 100 : Rebel will take more time
                                *Values that make sense 75-125


[Pruning = MISC_25]             * New reduction

* POSSIBLE IMPROVEMENTS (change the "?" to "=" to activate an option)
*
[Pruning ? MISC_17]             * skip first extension (speedup=20-25%)
[Pruning ? MISC17_DEPTH_11]     * Activate algorithm at iteration 11 and on
[Pruning ? MISC_21]             * Lazy Eval (tuning) (elo -10 / +10)
[Pruning ? MISC_29]             * Speedup (5%) (a bit risky)
[Pruning ? MISC_32]             * Single check extension (elo -10 / +10)
[Pruning ? MISC32_1.00]         * Margin for M32 = 1.00
[Pruning ? MISC32_MAX_2]        * Maxium allowed number of extensions for M32
(0-7)
[Pruning ? MISC_38]             * New capture extension

[Adjusted Selectivity MIDG ? 6] * Maximum selective depth (midgame)
[Adjusted Selectivity END0 ? 5] * Maximum selective depth (early endgame)
[Adjusted Selectivity END1 ? 4] * Maximum selective depth (endgame)
[Adjusted Selectivity END2 ? 3] * Maximum selective depth (simple endgame)

* 	Remaining active MISC options (probably not any good)
* 	Those marked with (!) are hardly tested a may have a future after all.
* 	Change the "?" to "=" to activate an option.
*
[Pruning = MISC_07]             * No recapture extension when capture is just
                                  a pawn (speedup=13%)
[Pruning ? MISC_08]             * Another crazy extension, probably not any
good.
[Pruning ? MISC_11]             * Skip reduction-1 as described at the
                                  Programmer Stuff page.

[Pruning ? SEX_MARGIN=0.60]     * 0.50
[Pruning ? SEX_HIST_DEPTH_4]    * 4
[Pruning ? SEX_MIDG_CHECKS]     * MIDG: CHECKS    = DOUBLE
[Pruning ? SEX_MIDG_CAPTURES]   * MIDG: RECAPS    = DOUBLE
[Pruning ? SEX_MIDG_PROM]       * MIDG: PROMOTION = DOUBLE
[Pruning ? SEX_ENDG_CHECKS]     * ENDG: CHECKS    = DOUBLE
[Pruning ? SEX_ENDG_CAPTURES]   * ENDG: RECAPS    = DOUBLE
[Pruning ? SEX_ENDG_PROM]       * ENDG: PROMOTION = DOUBLE

[Pruning ? MISC_22]             * Somewhat more safe Selective Search
(!)
[Pruning ? MISC_24]             * Skip first recapture extension (speedup=20%)
[Pruning ? MISC_28]             * More check extensions
(!)
[Pruning ? MISC_30]             * Only one escape from check extension
[Pruning ? MISC_41]             * Another crazy extension
[Pruning ? MISC_42]             * Reward first check as extension

[Pruning ? MISC_46]             * 6th rank extension
(!)
[Pruning ? M46_HASH_ON]         * Position must exist in Hash Table
(!)

[Pruning ? MISC_47]             * King Safety extension, nice but equal in
strength
[Pruning ? MISC_57]             * extension if dangerous pin
(!)
[Pruning ? MISC_65]             * research fail-high-error one ply deeper
(!)

[Center Control = 25]          * Center Control (50%)
(!)
. The [Center Control] parameter is now flexible
. Supported values: 0-500
. Values that make sense: 0-50
. When activating this option realize it will slow down the program with
  7-8% because of the extra chess knowledge.

[Bishop Mobility = 25]         * Bishop Pair (50%)
(!)
. Supported values: 10,15,20,25,30,40,50,60,70,75,80,90,100
. Activates a new piece of chess knowledge for the bishop pair.
. Values that make sense 0-50

[Right to Move = 75]          * Bonus for the side to move
(!)
. Supported values: 0-500
. Values that make sense: 0-150

[Strong Squares = 125]         * Evaluation strong squares (outposts)
(!)
. Supported values: 0-500
. Values that make sense: 0-250



[ANTI-GM = OFF]

[Extensions (remaining)= 3]
[Extensions (checks)= 0]
[Extensions (captures)= 0]
