[gnugo-devel] Tuning (trevor_1_24.4)

After this patch, with EXPERIMENTAL_CONNECTIONS on, the new breakage
is:

FAILS 13 
fails 3 
PASSES 26 
passes 2 
pass : fail 1.75 : 1 

Per Gunnar's suggestion, I'll leave [ox]play_connect disabled for now.

Here's my analysis of the breakage for all current CVS FAILURES.
Most are due to difficult owl problems.  Several notably have the
status of single stone groups changing, causing very different 
valuations.

13x13:25 FAILED        (serious) semeai problem.
13x13:36 failed        very hard problem.
13x13:39 failed        tough owl ordering.
13x13:65 FAILED        new pattern D1385 broke previous wrong solution.
arend:30 failed        B14 changed from CRITICAL to ALIVE (correctly).
global:14 FAILED       this one comes & goes
lazarus:14 FAILED      (serious) semeai problem.
lazarus:4 FAILED       difficult combination attack.
nicklas5:1202 FAILED   D10 stone changed from critical to alive.
nngs:150 FAILED        M3 changed from alive(!) to critical - right direction.
nngs:1520 FAILED       semeai problem (Changing matcher_status of D13 from 
CRITICAL to ALIVE.)
nngs:160 FAILED        see nngs:150
nngs:1690 failed       R14 changed from ALIVE to CRITICAL.
nngs:1700 FAILED       tough owl problem.
nngs:850 FAILED        Tough owl node-limit problem.
owl:46 FAILED          bad problem E3 also owl-defends.
strategy3:108 FAILED   (semeai?)
strategy4:194 FAILED   R15 is arguably a tough owl attack.
trevor:382 FAILED      shape tweeking; not serious
trevor:740 FAILED      missing owl pattern.
trevora:430 FAILED     F3 group change from CRITICAL to ALIVE.
trevorc:1250 FAILED    D2 group now correctly CRITICAL - wrong defense.
trevorc:1610 FAILED    tough owl concept.
trevord:520 FAILED     F17 stone changed from ALIVE to CRITICAL.
trevord:560 FAILED     M16 does give a tough attack on L17.
trevord:860 FAILED     same wrong concept as trevord:520
trevord:950 FAILED     passed by luck. CF3 correctly values another endgame 
move.
