[gnugo-devel] Difference between levels?

[Sanghyeon Seo]

What are the difference between levels of GNU Go?

I found that --decide-dragon results sometimes vary a lot between
levels. In one of my position:

Level 1: can be defended
Level 2: can be defended (uncertain)
Level 3: can be defended with bad ko (uncertain)
Level 4: can be defended with bad ko
Level 5-11: can be defended
Level 12: can be defended with bad ko
Level 13: can be defended
Level 14-15: can be defended with good ko
Level 16-20: can be defended with bad ko
My reading: can be defended with bad ko
