Bug ID: 429369
Summary: Very very slow to resolve
Product: kpat
Version: 19.12
Platform: Mint (Ubuntu based)
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: solver

Cpu running all cores.
SUMMARY
This is a fresh install of Mint 20 Cinnamon 64bit.
Running an i7 guad core processor w/ turbo boost to 4GHz.
Now and then the solver will run all 8 processors at 4Ghz max. Some times for
as long as 30 seconds or more.
STEPS TO REPRODUCE
Simply just load and pick a game. Normally the more complex games, like Mod3
or Yukon have a higher rate of displaying this issue.
OBSERVED RESULT
Oddly I observed when playing mod3 I had a choice of 2 Jack of spades to put on
a pile. Both jacks in the top line so it made no difference which I picked,
they both would go on top of the 8 and both free a hole. But one failed and
one did not.
Also as the game progresses, the symptoms diminish. Not unexpectedly since
there are less choices to test.
Sometimes I can back up and then 'redo' the move and it solves faster.
Normally I just assume it's having a hemorrhage and there is no solution so I
'undo' the move.
In Mint 19.3 I had a lag for the solver but never more than 10 seconds. And
usually it was 'cannot determine if there is a solution' or whatever the
wording is. A delay usually meant it was not a good move. Now it's just
taking time even to say it's still a winnable game.
EXPECTED RESULT
