Example games import missing ConstructFenceBias

[niclasso07-create]

Hi,

I am setting up the math-sdk from the current main branch and encountered an ImportError when trying to run the included example games.

For example:

python games\0_0_lines\run.py

fails because game_optimization.py imports:

from src.optimization.construct_fence_bias import ConstructFenceBias

However, ConstructFenceBias does not appear to exist in the SDK version referenced by requirements.txt.

The same issue also occurs when running:

python games\0_0_scatter\run.py

I searched the installed SDK source and could not find ConstructFenceBias or FenceBias.

Environment:

• Windows
• Python 3.12.10
• math-sdk current main branch
• stakeengine commit referenced by requirements.txt: 0842bb2

Is ConstructFenceBias missing from the pinned SDK version, or are the example games using an outdated/newer optimization API?

Thanks!
